Restaurant ON in Heidelberg

Five of us went out for dinner yesterday and ordered a large portion of seafood pancakes as a starter to share and five main courses. After about 50 minutes the seafood pancake was served and 10 minutes later the main courses arrived. This long wait became increasingly unpleasant. After we paid, I voiced my complaint to the boss. But their reaction was that this was all the customers' problem, they hadn't done anything wrong, and the wait was normal. A simple apology could have resolved the situation, but instead it made you feel even more uncomfortable. After reviewing negative reviews from other guests and the restaurant's responses, I quickly realized that such complaints are unnecessary - it's hard to expect a fair response from people who don't understand service. You can run your restaurant your way, but I can decide to stop going there and spend my money elsewhere.

Very friendly service and good quality food. The price is relatively high and we had to wait a long time for our food, so we deducted 1 star.

My family and I went to eat at this restaurant. It was very delicious. The vegetable side dishes were very delicious, the vegetables were crispy, and the price was not expensive. If there is a chance I'll want to eat again.

The food was delicious and the service was simply great, for me the best Korean in Heidelberg.

This was a bad experience in our life. We were there for dinner with our 6 months old daughter. We waited 15 mins to get our reserved table. Took 55 mins to serve our food, and by that time my little one was so cranky so we decided that will eat one by one. After my husband ate the food I gave my daughter to my husband and planning to have my dinner. They took my plate without asking me, and I had no food. That was a horrible evening. That was too much for me to handle. Unfriendly staff and zero management.

Our experience of the restaurant ON in Heidelberg was our worst in Germany so far. Me and my wife arrived at 6pm at the restaurant with our 6 month old daughter. As we had no reservation so we were provided a small table in the corner. We asked the waiter if there was a slightly bigger table available due to the bags we were carrying. They said no. We asked to make a reservation at 7 or 7:30pm depending on the time slot they had available. They said 7:30pm would be possible. We returned at 7:30pm. On arriving, we were asked to wait for 15min as there was no table available. We were called at almost 7:50pm at a table. After sitting at the table for 15-20min we were able to order. We waited and waited. Our order was brought to us after almost 30min. In the meantime our daughter became a bit irritated. My wife went outside with her to calm her down. She returned in 5min but our daughter not entirely calm. I finished my meal quickly and took over the task of calming our daughter. My wife helped me to put on the baby carrier and Coat at the door of the restaurant and then went back to complete her meal. On returning to our table, she found out that her meal was already thrown away and the table was empty. They thought we had finished our meals, even when the plates were full. We had waited effectively more than 3hrs and my wife had to leave empty stomach. As I said at the start, our worst experience in Germany. We would not recommend this restaurant at all.

I was there with a larger group, so that wasn't a problem with a reservation. We can highly recommend it. The food was great, unfortunately we were only missing the kimchi from the side dishes. But the Korean drinks made up for it.😉 The service was super nice🫶, helpful and quick. The toilet was also clean. So unreserved recommendation!!!! 매우 감사합니다 👍🫶

Super authentic and incredibly tasty! a nice excursion into Korean culture: the way the food is prepared, the polite details in the service. And also a highlight in terms of taste. We can only recommend it.

very bad experience，food very normal，and i have to wait over one hour to get my first dish，even there aren't many people eating，dont recommend👎

I must say the organization of the restaurant is too bad. Waiter and waitress are confused, and the kitchen is always ‚busy‘, even my food is not correctly ordered. After waiting 30min for my food, asking several times, one waiter finally realized that my order hadn’t been placed correctly 🤯🤯 However, to be fair, my starter is tasty, and the main dish of my friend seems nice.

If you love Asian and especially Korean cuisine, you should definitely take a look here. In addition to various dishes, there are also Asian drinks. And everything is beautifully presented too. Recommended

Had to wait an hour for the starter. After 1 1/2 hours of waiting we also got our main course. There were three of us there. I find the waiting time unreasonable. The food itself was ok. A little expensive, but you got enough. Service was also friendly.

Seafood soft tofu stew is delicious. The side dishes are also delicious. If you would like to order soft tofu stew as an appetizer with rice and side dishes, please order it as a Hauptgang (set).

The atmosphere inside was kinda cozy. The food was served in an appealing tray with tasty starters and appetizers. Main dish was the best. However we had to wait one hour to get our foods. Would definitely go there again, depending on my time!

Very bad service and miss order. Not only that, we did not feel welcomed and the female waitress was very rude and showed attitude when we requested to move from patio seating outside to inside before ordering.

I ate Korean food for the first time in my life and I absolutely loved it, really enjoyed it. The beef was nice and tender and the rest was also surprisingly tasty. The service is also very friendly. This restaurant is located near the old bridge.

The food was basically delicious, and the service brought you a new fork with the sound of the fork being dropped... It was really good

The price is 20-30 euros per person. The kimchi pancake is thick and crispy at the end. Stir-fried pork is a little spicy but delicious. The quantity is ample. The prices are similar to other restaurants, and it would be a good idea to stop by if you miss Korean food during your trip. If you are making news, it would be okay to just order the main meal instead of the appetizer. The service is pretty good at this level. Authentic korean cuisine, if you are craving Korean food in Heidelberg: go here. The kimchi pancake is great.

Great food with good portions. A little too loud in the store.

Kitchen is very slow, we waited for an hour to get food. Waiters didn’t check with us if we were happy despite many eye contacts, we saw people coming later than us get served before us. Bimbimbaq is dry, Seeweed roll is very salty (too much sauce), rice is soggy cooked with too much water. This restaurant used to be very good, now more expensive and worse food and service, I am disappointed with this experience.

You'd better book a seat in advance:)

Not a friendly boss, bad facial expression ever. Her attitude is ugly. We never met this kind of korean woman. Did not even greet the customers. not worth the money. Food taste wasn’t worth the price. I would never recommend this restaurant to anyone 👎🏻👎🏻👎🏻👎🏻 do not visit you guys!!!!

Specified opening times will not be adhered to. Kitchen closes 1 hour before closing time.

Honestly, the food is still really good (김치전 here is better than most in Korea) but unfortunately after it rebranded from Gogi it became very expensive and the portions became much smaller. The saddest part is that 두부김치 is no longer available 😢 If you don't mind the price though, I would recommend.

The food is good. Everything freshly prepared. Certainly not a bargain in terms of price, 4 dishes with 4 small drinks 107€. Unfortunately the waiting time for the food was a bit too long.

The kimchi pancake was the perfect hot starter. The seaweed and seafood pancakes were good too, but the kimchi one really stood out. For our mains, we had bibimbaps and they were delicious. I do wish there was more of the hot sauce that comes with it. Pro tip: let the rice sit at the bottom for a bit so it gets nice and crunchy before mixing everything together. Just be careful not to leave it too long, or it might burn. The aloe vera juice was nice, but it's a bit too sweet to have before your meal. It would make a great refreshing dessert after your food.

The food was good, albeit pricey. The location is lovely, very central and the restaurant is quite large. The service was very slow even though there were not that many people inside and outside. And the server forgot the drinks we ordered.

Best Korean food prepared very tasty. Extremely impressive taste events. Plum spritzer smart. Service perfect. Now number one for us in HD, good value for money. We will be back!

Very good offer. Staff very friendly!

The absolute best Korean in the Rhine/Main/Neckar area in my opinion. The atmosphere of the restaurant is more in the style of an old German restaurant but you still feel comfortable. I have never eaten my favorite dish, Osam Bulgogi, to such perfection anywhere else as at On. Keep it up and I absolutely recommend it. We easily got a bowl of rice for my 2-year-old niece, and there was even children's cutlery

The pancake was crispy and very delicious! The spicy stir-fried pork was very spicy.

At the end of my three-day trip to Heidelberg, I visited On, a Korean restaurant on the banks of the Neckar. It's neat Korean food. Stir-fried pork and kimchi stew were just as delicious as those at a Korean restaurant. The German customer at the next table seemed to like the stone pot bibimbap, too. It was a dinner suitable for a beautiful spring night in May. We met at a Korean restaurant in Germany. My wife and I were lucky to have a hearty dinner. I hope “On” continues to do well in the future. Thank you.

Korean food is tastier and cleaner than what you get in Korea.

I recommend you try the udons which are delicious!

the freshness and quality of the products was great! The service was very courteous and professional

Always fine food and excellent quality!

There are already enough photos of the restaurant, but I think that when I write that my wife said to me that I haven't looked so satisfied and happy after eating in a long time, it hits the spot! 🙂 And the fact that several Koreans came to eat while we were there also says a lot; they will appreciate good and authentic local food.

Highly recommend the tteokbokki, authentic flavour, generous portion of fish cake. Do add on ramen as it can soak up the gravy, enhancing the flavout and making it suitable for sharing. The kimchi pajeon can do with less flour as it was a little too thick. Staff are friendly and attentive. Reservation easily done from the restaurant’s website.

A taste that can survive even in areas with many Korean restaurants, such as Berlin, Frankfurt, and Hamburg. Bibimbap was the most delicious I had in Germany. Osam bulgogi is comparable to Korea's with the right fire flavor and the harmony of vegetables and seasoning. Despite the slightly disappointing price, I immediately think I'll go again the next day.

I'm a big fan of Korean cuisine and have been to South Korea several times, so I know exactly what the food tastes like there. Unfortunately I have to say this restaurant is not authentic. It's super expensive for what you get. Unfortunately I'm a bit disappointed😅 I had bulgogi 7.3/10 I don't know, it shouldn't taste like that. My buddy had udon noodles 7.5/10 was okay. Soju soda was too small for the price. The banchan were good though. The chopsticks weren't Korean at all, I don't like them, I've already deducted points because of that...

The service is super good. The food is super delicious. It has a Korean taste.

Very good food, but the staff was very unfriendly and the service was poor. After the food was brought to the table, no waitress came to take drinks. There was also no friendliness when paying, which was very sad because it definitely doesn't make you feel welcome and tends to drive customers away.

Really very good Korean food. The restaurant is large and offers plenty of space. The service is good and fast. Unfortunately the prices are way too expensive for my taste.

The best Korean I've been to. I love Korean food and was not disappointed. The visit to the restaurant was a dream. We had made a reservation, arrived 15 minutes in advance and were warmly welcomed and shown to our seat. The waitresses were all extremely friendly and helpful. Our questions about the menu were explicitly asked in the kitchen. So we were very satisfied before the food came. When we received our extremely delicious food, it was clear we would be back. We ate the udon noodles, the entrecot and the spicy chicken strips with mozzarella. Each of these meals was simply incredibly tasty. The meat was tender and the small side dishes that were served with it complemented the meal very well. All in all a perfect visit to ON. Thank you for this lovely stay on Friday evening.

I come to Heidelberg really often, but the reviews on the Korean Pavilion have been so bad these days (maybe the owner has changed), so I came here on purpose. I ordered tteokbokki, dumplings, and something similar to jeyuk and kimchi rice bowls, but the only thing worth eating was the pork kimchi rice bowl (I can't remember the exact menu name). To be honest, the tteokbokki was worse than the special tteokbokki from Kimbap Heaven in Korea. And dumplings... You priced 5 pieces of hometown dumplings at 7 or 8 euros... Even American restaurants use bibigo when selling them... Please note. The service was really good. Maybe the menu I chose was a disaster... P.S. Yes, master. It's true that I visited the Restaurant on. I looked it up and found that the name of the food I ordered was Cheese Chicken Ribs. And tteokbokki dumplings. Would I have written a review without even visiting? Instead of getting upset by bad reviews, it would be a good idea to refer to them to see if there is anything that can be improved.

Went there for the first time and it was very tasty.

Definitely the best Korean food in Heidelberg!

It's so delicious. It's not just that it's delicious because it's been a while since I've had Korean food, but the food itself is delicious. It tastes better than restaurants in Korea. They give me a lot of food too. I wanted to eat more, but I was full. A restaurant I want to come back to again~~^^

Excellent. We waited just over 20 minutes. You'll be super full without feeling like a fat comma afterwards. The prices are reasonable. Any time :)

I was there right at 6 p.m. in the evening. After an hour the restaurant filled up, so I would recommend a reservation. The atmosphere was nice and the service was very friendly. I felt very comfortable. The food was great. I had fried mandu with pork and bulgogi as my main course. You get various side dishes with the main course and will definitely fill you up. The prices are a little higher, but you get something for it. Definitely a recommendation for anyone who wants to eat authentically Korean food.

This is the first review I've ever written and I'm only writing it because I'm so convinced of the On. The food is 10/10 (especially the Jeyuk Bokkeum but also the seaweed rolls) and the service is also very good (very nice, yet reserved). The ambience is so mediocre but if you go to a restaurant for the ambience you are lost.

Very(!) nice food with extra portions :)

Traditional Korean restaurant...

Komme immer wieder gerne! Aber man sollte vorher reservieren

Sehr überzeugender erster Eindruck der koreanischen Küche. Die Aufbereitung war ebenso sehr gelungen!

Leider stimmt das Preis-Leistungsverhältnis absolut nicht mehr. Ich verstehe ja das durch sie MwSt die Preise steigen aber 15€ für Kimchi Jeon - Nein auch wenn er gut war. Das Bulgogi war zu süß. Insgesamt war das Essen aber okay, gibt besseres in HD... Abzüge gibt es vor allem für das Ambiente, zu mal es brutal zugig und kalt war, war kurz davor in Jacke zu essen... Wir haben zu zweit 100€ bezahlt, das ist es sicherlich nicht wert!

Fried chicken was delicious, thanks!

Das Essen ist ziemlich gut, das Ttoekbokki ist nur leider überhaupt nicht scharf gewesen. Der Service ist in Ordnung. Die Dame, die schon länger da ist, ist sehr nett, aber beim letzten Besuch haben wir 40 Minuten auf unsere Vorspeise gewartet (und auch dann kam nur eine von zwei) und das Essen kam auf Nachfrage nach über einer Stunde. Daran kann man arbeiten, ansonsten kommen wir hier eigentlich ganz gerne hin.

I have to say that the food in this restaurant is not very delicious and not fresh. The taste is still very different from authentic Korean food. If you want to taste authentic Korean food, there are two other Korean restaurants in Heidelberg that are very good choices.

Großartiges Essen und sehr guter Service!

Wir hatten einen fabelhaften Abend im Restaurant. Online Reservierung möglich. Nette Bedienung, prompte Bestellung. Restaurant war gut besucht. Speisen hervorragend in Qualität und Geschmack. Wir kommen wieder!! Ambiente schlicht gehalten.

돌솥비빔밥은 볶음밥느낌이고 김찌찌개는 먹을만함. 친절함은 느끼지 못했어요

Top Geschmack. Top Portionen. Top Preise.

오늘 하루 두 번 갔네요. (아마 누군지 아실듯 ㅋㅋㅋ) 정말 잘 먹었습니다. 한국만큼 맛있는곳이였네요. 정말 뮌헨으로 이사오셨음 좋겠네요 ㅎㅎㅎ 떡볶이, 치즈닭갈비, 제육볶음, 비빔밥...뭐 하나 맛없는게 없었습니다.

Das Essen war gut, nur war es im Restaurant nicht wirklich warm. Die Einrichtung etwas spartanisch, und leider verstand die Bedienung das Wort "Muscheln" nicht... 😳

Sehr nettes Personal und das Essen ist sehr lecker 👍🏼

Gebratener Udong war sehr geschmeckt die Service war freundlich.

Mein erster Besuch war fantastisch, dies ist mein zweiter und ich war schockiert vom Service, sehr schade. Wir haben 2 Vor- und 2 Hauptspeisen bestellt. Eine Vorspeise kam nach ca. 40min. Nach 1h10min fragten wir, wann das restliche Essen kommt. Die Antwort darauf: "Ihr hattet doch eure Vorspeise." Diese Reaktion war sehr unangenehm, ich zeige gern Verständnis, wenn mal was schiefläuft seitens des Restaurants, doch sowas geht gar nicht. Wir fragten:"Okay, und was ist mit der zweiten Vorspeise und den 2 Hauptspeisen?" Keine 5min später wurde alles auf einmal wortlos an den Tisch gebracht, vermutlich wurde das Essen vergessen, denn warm war es nicht. Zum Essen, es hätte scharf sein sollen, und das war es kein bisschen.

Das Essen war sehr lecker. Personal sehr zuvorkommend. Tisch am besten reservieren, da sehr gut besucht.

genieße das Ambiente im einzigen authentischen koreanischen Restaurant in Heidelberg.. 👍

Gutes Essen, schlechter, absolut unqualifizierter Kellner, der Bestellungen fehlerhaft ausführt, ohne Entschuldigung das Diskutieren anfängt und seine hilfsweise dazu geholte Kollegin mit unfreundlicher Mine sein Defizit auch nicht auszugleichen vermag. Das gute Essen wurde leider durch den überaus schlechten Service mit langen Wartezeiten vermiest. Kein zweites Mal. Schade.

Über eine Stunde auf das Essen gewartet. Geschmeckt hat es, aber der Hunger war leider schon weggewartet.

Het eten was lekker. Leuke extra schaaltjes.

It's ok, not more. The food tastes decent but that's about it. The staff doesn't appear to be on top of it. All in all a mixed experience which I won't have again.

Great and authentic korean restaurant in Heidelberg

Service ist toll, ich wurde mehrmals höflich in angemessen Zeitabständen gefragt ob ich gerne noch was hätte. Das Restaurant ist sauber und hat sehr schöne Dekorationen, ohne dass es zu viel ist. Das Essens wurde sauber und schön präsentiert. Das Essen macht tatsächlich satt und meistens bleibt etwas übrig. Preislich sind die Preise den Gerichten entsprechend angepasst und es gibt eine gute Wahl an Getränken, sowie Alkohol:) Dadurch, dass es leider in der Innstadt ist, gibt es Treppen zum Restaurant rein, auch wenn es nur ein paar Stufen sind, ist es nicht für Rollstuhlfahrer geeignet, jedoch bin ich mir nicht sicher, ob man auch draußen sitzen kann 9/10

The bibimbap is really good. Highly recommend

Very nice Korean food restaurant, but always busy, especially on weekends, requires reservations.

I don't have a lot of experience with Korean food, but overall, the taste was okay. However, I expected much more flavor and found it rather bland, except for the spice level, which was good. A more significant issue was the rude waitress who had zero patience right from the beginning and was obviously very annoyed by the stress our big group seemed to have caused her. Her behavior was truly unprofessional and everybody in our group noticed it. I would describe the location itself as average - really, nothing special.

Restaurante con opciones veganas. Comida sabrosa, y cuantiosa. Las bebidas típicas coreanas son algo caras pero merece la pena probarlas. Servicio agradable.

Leider war der Service überfordert und es war sehr laut im Lokal.

Sehr leckere authentische Koreanische Küche . Immer frisch und lecker , besonders zu empfangen die Udon Nudeln. Vor einem Besuch am besten reservieren, da das Restaurant immer sehr gut besucht ist

Wir mussten zwar eine halbe Stunde auf unsere Getränke und eine Stunde auf unser Essen warten, aber es hat sich wirklich gelohnt. Das Essen war sehr lecker!

Non male questo ristorante in centro

An all-round good experience. We all enjoyed our meal. A little patience is required when they are busy. Friendly staff.

Das Essen war sehr fein und reichlich. Wir hatten reserviert,trorzdem haben wir über eine Stunde auf Vorspeisen und Essen gewartet. Fanden dies gar nicht so schön.

Man hat sich sehr aufmerksam erkundigt, ob ein komplett veganes Essen zubereitet werden soll, als wie das bibimbap bestellt haben, was sehr zuvorkommend war.

Nicht authentisch, Gerichte nicht besonders gut zubereitet schlechte side dishes.
