I Koi Sushi Restaurant in Heidelberg

Everything is really delicious and the staff are super friendly. Nevertheless, €31.80 per person without drinking is a lot of money. But if you're hungry enough, you'll definitely eat well for the price. You have 2 hours and every 10 minutes you can order 5 things per person. There were two of us there and we only managed 5 laps.

Great food! Very nice staff, like to eat there :)

Service = 0, unfriendly, you ask questions and the waitress just keep going instead of listening

Tried every single dish at the all you can eat. Just disgusting

It was Monday evening, and the place was fairly empty. We ordered eel and teriyaki chicken (I took the duck option). You can compare the advertised photo and what we actually got. No miso soup, no edamame. False advertising? The duck was too dry and slightly overcooked (?). It was not crispy in a good sense, but kinda dry crispy. The price is low probably because most of the dish is just (not very good) rice. Even I can cook better rice with my ricecooker at home. Also bento boxes are only for lunch, despite having the advertisement poster for them in the evening. Maybe their sushi is good, I didn't try that. Either way, I will not come back.

The food was great! They had a great selection with good value for money. We chose the all you can eat option, where you can order a round of 10 dishes every 10 minutes. You can order up to 10 rounds in total within 2 hours. However, we were full after just 4 laps. The only thing I have to complain about is that they gave us a card at the beginning and we were only able to do the all you can eat when we explicitly asked. The service staff was super nice and the food came very quickly.

The lunch menus are unbeatable. Price-performance top! Buffet is also great!

Very tasty food with a nice atmosphere and very friendly service!

Very poor quality and an associated poor price/performance ratio. The only positive thing about the restaurant is the location. The customer service was also subpar. All in all, not a nice restaurant experience. Hopefully the owners take this feedback to heart. LG

Unfortunately, the restaurant disappointed me greatly today. I visit the restaurant probably twice a month, celebrated my birthday there only to be turned down for lunch today because there were too many guests in the restaurant, but there were still seats available. If I offer a certain concept as a restaurant, then even if the restaurant is full. It's a real shame, but luckily there are alternatives in Heidelberg that I'll look for in the future.

Went to this restaurant for the first time. The food was super tasty, fresh and was really well prepared: your eyes always eat with you. The staff was personable and friendly. We always received our orders quickly. I had a great time in this restaurant and was very satisfied. Next time I'm in the mood for sushi, I'd be happy to stop by. Highly recommended.

Very tasty and the employees are very nice and accommodating.

Tastes good, I can recommend it

This restaurant always exceeds my expectations.. The sushi is really great! The ingredients are fresh, the rice is perfectly prepared, and the fish tastes incredibly good. The service also deserves high praise. If you love good sushi, you should definitely stop by here – highly recommended!

The sushi is reasonable and tasty for the price. Ambiance is okay and location is right on the main street. Service is normal. The lunch menu is recommended, really good prices for a large portion of noodles and soup. Udon noodles for 4.80 per portion are mega tasty and large.

Food is good (not superb but good), and especially in that price range, that’s a really good worth of your money. Staffs are nice. I really like their lunch menu and once I came a bit too late, they still served me the menu even though it was dinner time.

Fresh fish, excellently prepared. Pleasant service.

All you can eat for ~31€ per person. Ordering is done via tablet in rounds. It tasted great and service was friendly.

Travel an extra 2 hours for the great sushi and the numerous all-you-can-eat specialties. Ordering is conveniently carried out on a tray. Definitely a recommendation

Had the tablet all you can eat version. Taste very good. Friendliness was good and it was always cleared away. I've been there four times so far and everything has always been fresh.

The orange sushi with salmon and home made teriyaki sauce was so good!

Service was very unfriendly, food was good and even though we had specially reserved a table, we were put at the line and were told that what was wrong had already been said on the phone and after we were asked, they asked where they wanted to sit and were then able to sit at the table

Service and prices are too high. Food is good.

In the central street, spread over several floors and various rooms, standard and bar tables with roller fronts. Sushi in various modes or combo menus as per flyer or order from the full menu. Chinese, Japanese and Korean offerings (there was kimchi). The courses are cheap and accessible for a quick, satiating and tasty lunch. I also had the chance to taste the broth of the ramen and it was a nice full flavor.

Wanted a change from German food, was walking past at dinner time, the lunch menu was still advertised outside, cooked dishes in Bento boxes, when we were given a menu with just sushi we asked about the menu outside and was told we could have the main courses which was great as this is what we wanted, teriyaki chicken, rice and vegetables and it was lovely, so tasty. Had little Moons (Mochi) for a dessert again nice and well presented. Service was fine, the servers really earn their money. You might want to make a reservation as it was really busy

The staff is very friendly. Food was good, the noodles were a bit dry.

Ultra slow and far too little for the price, not recommended, absolutely not good for €30

We had a great time there :) The food tasted really good, the price was great too and the service was really quick and more than friendly. We would go there again and again!

I go Imizu for eat Buffet, i really like their food especially Salmon 😍 The staff also friendly.

Hair in food :( Not just one, but a bundle!!! When asked, the hair was dismissed as black strands of eggs. Zero insight or apology. Sorry, this reaction doesn't work at all! Luckily it was the first plate to be delivered. We then left the restaurant. We hadn't gotten any drinks at this point.

Seeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet and deliciousrrrrrrrrrrrr! Thanks

I often come here for the lunch menu, a huge portion for 12.90, you can fill up for lunch and dinner (but I don’t recommend ramen, they are much tastier), but the waiters are very friendly and remember that I need a fork)) There is a favorite table by the window right on the main page the street where I always sit is completely empty during the day and you can sit anywhere, and the place itself is huge, so it never happens that there is nowhere to sit.

Ate here for the first time yesterday (in the evening, 2 starters, 2 main courses, 3 drinks for only 37 euros), and came back today for the main course and dessert 😁 Tasty, quick and cheap too! 🙏🏻

Very good lunch & sushi. Friendly staff.

All you can eat in the heart of the historic old town. There is currently only one table outside and we used it to enjoy this special atmosphere. The atmosphere inside is nothing special. We have been visiting Imizu in Frankfurt for over three years, and when we heard there was a new opening in downtown Heidelberg, we had to try it out. The food quality was, as expected, good – typical of Imizu. The selection is similar and we were recommended to try the mango sauce, which is not available in Frankfurt - it was delicious. The equipment is older and smaller than in Frankfurt, and I also like the atmosphere there better, although the location in Heidelberg is perfect. But if you have nice weather, grab this table outside – we got really lucky! 🍣

The truth is, if you have known places with minimally decent Asian food, this one will surely disappoint you. The service was not very fast, but not excessive, but the food was nothing special, a feeling of doing it quickly and without much interest. Perhaps by not choosing the buffet option we were a little more demanding with what we expected, but if you eat that at a buffet, perhaps you accept the quality of the presentation and the products. Everything is correct, but it is better not to have high expectations.

Great sushi dinner with clearly good quality ingredients. Lovely service. The 23stk sushi boat and a big coke cost me about 25€. I feel it’s reasonable for the quality!

To start with: I can eat quite a lot and have a sensitive stomach when it comes to the freshness of the products. This means that even mediocre quality meat at an all-you-can-eat restaurant upsets my stomach. I gave the Imizu full throttle for 2 hours and I'm in great shape. - Everything is freshly prepared, tastes great and is tolerable. - In terms of taste, Imizu is definitely above a conventional all you can eat restaurant Recommendation: Iced peach tea, homemade

Delicious, fresh food at absolutely correct prices. All-you-can-eat would have been average for us. Not worth eating, we were so full. We would love to come back here.

Asian: YES; Japanese: NO Plus point when eating: lots of vegetables in the soup. Otherwise not Japanese. The staff also doesn't speak Japanese. Service: The staff on the day of the visit was quite slow. Waiting 25 minutes for your lunch during your 1 hour lunch break is unreasonable.

I can only recommend the Imizu. The food is very good, tastes fresh and arrives at the buffet at good intervals, so you'll want to eat more. I really enjoy going here with friends, as the restaurant is a good place to meet up and have a long chat over a meal. You can pay in cash or by card.

The food was really tasty 😋, the atmosphere was nice, nice people, cleanliness was great. Recommended!!!!

We got a table even though we accidentally reserved at Imizu Franfurt.

The Uber Eats driver took my sushi meal order from the counter and left without asking or knowing if the order was complete. Well, the seaweed salad, ginger, wasabi, soy sauce were missing. The problem was quickly resolved over the phone. Even though I had at least received the sushi set, the restaurant refunded me the full amount and apologized. The fault was clearly not yours. Thanks!

We had buffet for dinner. The food had good quality as a buffet, but they were very slow! The buffet allows 10 rounds of ordering per person within 2 hours, with 10 mins break. When we ordered the six round, there were still quite some dishes from the second rounds did not reach us. So in the end we didn’t have the chance to try the some food we want. And they also didn’t not give us discounts or vouchers. Considering these, the price of more than 30 Euro per person for buffet is not worthy.

Imizu offers an excellent all you can eat experience that is totally worth the price. Particularly noteworthy is the sushi, which is freshly prepared and impresses in terms of both quality and taste. The variety of sushi variations ensures that everyone will find something suitable, and even connoisseurs will get their money's worth here. In addition to sushi, the buffet also offers a good selection of warm dishes, so there is something for every taste. The atmosphere in the restaurant is pleasant, the staff friendly and attentive. For sushi lovers and fans of Asian cuisine, Imizu is definitely worth a visit. Not only is the price right here, but also the quality of the food. An all-round successful All You Can Eat experience.

Very tasty food with a nice atmosphere and very friendly service!

Went there for lunch and chose the tablet buffet. Super fair price and very tasty food. We tried the Japanese cuisine once and had so much fun because everyone could try each other and then order what was good again for themselves. The staff was also great! We'll definitely be back.

The service was very slow, not reliable and cannot be recommended. The food wasn't anything special either. It's best to look around for other restaurants.

We happened to walk by here and saw their menu which we liked. Nice clean place with friendly staff. Very helpful and the food was really good. Here you can eat well and sit comfortably. The restaurant has two floors and is very large, we saw this because the toilet was upstairs. Very good choice to eat here.

Food: 4.5 stars, I found it very tasty, nothing amazing but definitely recommended. My girlfriend also thought it was good apart from the cucumber parlor, so half a star was deducted. Ambiance: 4 stars, very nice and beautiful shop, but wasps came the whole time because the doors were open and there was only one song playing the whole time. However, all in all great. Service: 7 stars preferably, super super nice, the nice waiter was amazing. He asked us a lot if everything was okay, beat the wasps away for us, was super friendly and at the end he even gave us a free sesame ice cream each, which was also very good. Recommended for this service alone, and of course also for the food :)

We actually had good experiences until we were there with a child for the first time yesterday. Obviously this can only be 1.50 tall, at 1.53 (although the small one is never that big) you can no longer pay the children's price for "all you can eat". We only accepted that and ordered from the menu for the little one when the Kellern came back, with the note that the little one (THOUGH we had already ordered from the Katte for the little one) should NOT be from the other “all you can eat” Eat your orders and definitely don't try them. It was clear to us that we would get up and go. He was unfriendly and unfortunately couldn't handle criticism. Also from an economic point of view, absolutely stupid. Anyone who lets customers go for over €100 for €5 when the little one might have tried something has probably taken too much out of their mouths. It's a shame, but we won't be eating here again.

The iPad order is awesome. The portions you get with the all you can eat are sample portions which were perfect for the experience. Reasonably priced but not great either. The building has no air conditioning so it can get quite warm and the staff were nice but sometimes they seemed uninterested.

The portions were large and everything was very tasty! The service was also very nice and quick. 👍

If you like sushi, this is the right place for you. Great all-u-can-eat system. You can choose 5 small dishes per round (10 minutes) and person. Very good for chatting together and sharing sushi and other delicacies.

All you can eat of good quality.

Ate very good sushi here! My husband ordered the salmon salad and I also ordered an onigiri. Everything was really fresh and delicious! We can only recommend it!

Nice staff, good system with the iPads for self-ordering. You don't always have to wait for a waiter.

The staff is very friendly, they too have become Druze. good, of course, delicious food especially udon noodle

Delicious food and good service, although we had a hard time making ourselves understood due to our bad English. All very well

Very satisfied because the ingredients were very lovingly handcrafted and very well processed. We'd love to come back

A variety of lunch menus are available. In particular, there are many types of bento with competitive prices, and the raw sushi ordered is of the quality you can find in Asia. However, what was a little disappointing was that the rice included in the bento was rough and hard.

A huge store behind a small entrance. Even two levels including a place in the sun. Running sushi in the evening, cheaper and excellent lunch during the day Other Japanese specialties are also on the menu

Were here this Friday evening for all-you-can-eat. It was terribly warm in the restaurant and the tables were far too close together. The food is ordered via a tablet with outdated software and still shows the former name of the restaurant. The fried/fried foods were all very greasy. Spring rolls like they come from the freezer with “Asian sauce” from the supermarket. That's not bad in itself, but it's disappointing for €31.80 per person. The chairs were comfortable and there was also a selection of vegan and vegetarian options. However, I would not recommend the restaurant, especially not during rush hour.

We had reserved a table for 12 people. Half wanted that Take the buffet and the other half preferred to order a la carte or weren't that hungry. But this was not possible. Unfortunately, when we ordered we were told that either everyone had to take the buffet or everyone had to take it off the menu. When asked what the reason for this was, it was stated that those who ordered tickets could eat with the buffet eaters. I found this to be completely non-customer oriented and implied that we were abusing the offer. I think it's an impertinence to tell one of our companions, who is very careful about his calories, that he has to take the buffet or the others can't use the buffet because of one person. First of all, this restaurant is not very big. You could look directly at our table from the entrance and reception. It would have been easier to see if we had sat on the waiter's lap. Apparently the restaurant is designed for tourists who get paid once and don't care if they come again. But as a person who works in Heidelberg, you won't go here anymore. The sushi was tasty and OK. I would like to give this 3.5 stars.

i ordered alot of variety of the sushi options from your menu and when i say it was not fresh at all it is an understatement i could not eat it and hopefully noone goes through what i did with their sushi. I too this day cannot order sushi because of this experience maybe one day i can give sushi another shot but for now i will not be going near it because of this restaurant.

The food in this restaurant was excellent and tasty. The prices were reasonable and fair. Unfortunately, there were problems implementing our All You Can Eat orders. There was a mix-up and, as a vegan, I received dumplings filled with meat. Since there were two of us who ordered and didn't question every dish, this was particularly annoying. It's pretty annoying to still be served meat in a restaurant where I only order vegan food and explicitly ask for some dishes.

The sushi restaurant on Heidelberg's shopping street, which looks somewhat inconspicuous from the outside, has two large dining rooms on two floors. We ordered the all-you-can-eat buffet via iPad, which is hardly advertised (ASK!). The selection is large, the portions generous. We were very impressed with the quality of the food. The service was very attentive, quick and very friendly. Unfortunately we were just passing through Heidelberg, otherwise we would certainly be regular customers.

Became very expensive and the service was below all...! The food was okay.

Wow. Very very tasty. Good choice. On the conveyor belt and per person 5 dishes from the menu with a short waiting time. Absolutely delicious. 😋😋

Simply great. Super freshly prepared. The salad couldn't be fresher. The food comes to the table hot. The staff is very friendly and the small but nice restaurant offers the perfect ambience. We've been coming back for years 🤍

Payment: We tried to pay with four different debit cards (2x Germany and 2x US), all of which the card machine declined and the waiter blamed it on us, and then blamed it on the rain? I’ve never experienced service like this before…. Food: The sushi is good (for Germany standards) they do an all you can eat lunch or dinner buffet. However they stopped us ordering sashimi for no reason. Staff: They don’t speak English so it was tricky to communicate as a tourist. The older man was not very customer friendly.

We had the all you can eat and it was all very tasty. Unfortunately we only managed 3 rounds, but it was still totally worth it in terms of price. We couldn't do it anymore after that. The only criticism is that the tablet doesn't say how many pieces of sushi there are, for example, so we accidentally ordered 16 pieces because we thought a portion was about 4 and not 8. But it wasn't bad because they were small and totally delicious.

nice atmosphere and staff. Great food for good price. I can recommend it.

Nice sushi. Not a lot of vegetarian options but decent prices and a good variety for others.

Very tasty food with a perfect portion size. We had the lunch dish which had different things on it :)

Sushi portions are no longer too big as they used to be <bite-sized> Other dishes were also very 👍 It tasted very good. We'd love to come back again

Very interesting selection of sushi, special and delicious!

Very good restaurant. Responsive staff, delicious food and cozy atmosphere.

Eating under time pressure (a maximum of 2 hours is allowed, otherwise we would have been thrown out of the restaurant) and "all you can eat" which is not a real all you can eat. Service very rude. Absolutely not recommended

Delicious! Very fresh and top quality! Very fast, very friendly service! Increased by 1000% compared to a few years ago! Really TOP!!! We would love to come back 🫶

Quite nice 🫶🏼 We did “all you can eat”, which now costs around €20 pp. The sushi was sometimes better, sometimes worse, but really okay for what you get 👍🏼

Completely satisfied. Food and service top!

Very convincing quality, delicious sushi, but also good small main courses such as beef or calamari. The price is a bit more expensive, but worth it for the variety on offer and unlimited food!

The best buffet in Heidelberg! I have visited this restaurant several times and am always impressed. At €21.80 per person for lunch (drinks not included), the buffet offers excellent value for money. I always like to order lamb skewers, sweet potato fries, seaweed salad, miso soup, baked banana and lychee. There are also many sushi offerings. In total, each person can order 10 rounds, but after the fourth round I'm completely full. I will gladly come again!

Everything was very tasty and not as expensive as other restaurants. I recommend it with all my heart 🙌

We had a very nice evening at Imizu. The food and service were great!

Incredibly delicious sushi in Heidelberg's old town. We have never eaten such delicious sushi. It is freshly prepared and served with a lot of love. The price is a little higher, but it's worth it. You have 2 hours and can order on the tray and take food from the conveyor belt. The only criticism: Please cut vegan sushi with an extra knife, fish roe on veggie sushi is unsightly.

Contrary to some reviews, the Sushi Band is operational. In addition to the belt, all dishes can be ordered via a tablet if you haven't found your preferred sushi or want to eat something else. If all you can eat is too much for you, you can also choose dishes from the menu. We were there for lunch and had a wide variety of dishes available. We will definitely test whether the menu is even richer in the evening.

The selection is very nice and the food was also very tasty. Unfortunately, the sushi is sometimes a little dry, but this can be changed with soy sauce. The own sushi creations are a little more expensive, but we enjoyed them very much. We also ate wontons, which were also very good. Unfortunately, the all-you-can-eat is mandatory because the sushi is quite small and otherwise the whole thing would not be worthwhile for the guest. The furnishings, especially the chairs, have seen better days. It's not incredibly bad, but it could be avoided. Conclusion: It is a solid sushi restaurant that is worth a visit. (All-you-can-eat is important!)

For €31.80 you can have an all-you-can-eat evening meal, although this does not take place at a buffet, as is misleadingly advertised. Instead, guests have the choice of using the conveyor belt or ordering via an iPad, with all dishes delivered directly to the table. One advantage of ordering at a table is that the dishes are prepared fresh without having been on the conveyor belt for a while. It is also possible to order à la carte. The sushi selection isn't very large, but the taste is okay.

Has fallen significantly compared to before (until 2019), sometimes worse food, less selection at a significantly higher price! We used to go there often, but probably won't do so anymore! We were absolutely disappointed, what a shame!!! We had the buffet!

Very tasty and the fact that the all you can eat is ordered via tablets and brought to your place is very pleasant.

Price-performance is great and the sushi is very tasty!

So delicious! Everything fresh on the table. Pleasant atmosphere. We will be back!

Unfortunately, the quality has decreased significantly and the prices have increased. All you can eat costs €31.50 per person, which is far too expensive considering you only get fried ready-made food. The sushi wasn't particularly tasty either. I actually wouldn't eat there again after my last visit, there are much better options in Heidelberg :)

Very good food,☆ But employees are slow, they waited 30 minutes until we could pay. Otherwise great👍🏻💛

Perfect location, food and atmosphere

We love the IKoi. I really can't understand why it has so many bad reviews. The selection is very tasty, you order smaller portions (like Japanese tapas) using a tablet and pay a flat rate for them. The selection is good and the quality of the food is very tasty. The service has always been super friendly.

Very rude service. We reserved a table by phone for my birthday at 4 p.m. When we arrived we were made to wait a few minutes. The question then came as to whether we wanted to stay away from the crowd!? When we were assigned to a table inside as requested, we sat down. The waiter (older man) gave us three cards, whereupon I asked if we could also get tablets as usual. He ordered me very rudely: “Look at the clock!”. (For your background: All You Can Eat orders with tablets are only possible from 4:30 p.m., which we didn't know and nobody pointed out to us on the phone or on site). He also answered other questions cheekily, which is why we decided to leave. It's a shame that you are treated like this as a guest. We were looking forward to the food.
