Unfortunately, the food has nothing to do with the original :/ It would certainly be edible/delicious in its own right, if they weren't so obsessed with pseudo-Japanese cuisine.
Perhaps it's well-adapted to German customers—but for those with Japanese roots, it's truly inedible. (Psychology plays a big role here—if you don't expect anything Japanese and aren't terribly disappointed with the food, it probably wouldn't be so bad.)
Service particularly unfriendly. Even if the menu is extensive, not even half of it is available. You are treated rudely. The chef and cashier look irritated when you ask for a simple meal. When you ask what's on offer, the cashier suddenly becomes annoyed and makes little effort to show interest in the customer's order. She asks customers to read the entire menu, but she won't give any information about it if you ask nicely. If you decide on a dish, the cashier simply says: “We don’t have that”. Why do you open a restaurant if you can't even ensure that the food is available?
Actually, it was always great here, and the food was okay for such a small restaurant.
Unfortunately there has now been a change of ownership.
1.) no more food
2.) After 10 minutes we were asked if we wanted something to drink.
3.) new owner not very friendly.
It's now just a small corner pub in good German.
