I like spending money on good sushi... And this is good sushi. The fish is fresh, the preparation very good. But it's just too expensive. Not that I would mind spending that kind of money on sushi - but then it has to be world-class,...More

The Japanese Restaurant Unkai is a special example of exquisite service and fascinating delicacies of the Japanese kitchen.

Dishes like Sushi and Sashimi are prepared on the highest level, the Teppanyaki grill being the most popular way of preparation. Two original Japanese Tatami rooms as well as two European dining rooms are available for private dining.

Special highlight is the exclusive Sushi-Brunch, offered on weekends and public holidays. On Thursdays, one can enjoy the after work sushi buffet. Various Bento-boxes and Sushi-Sets are also available for take-away.
