We were surprised to find a decent Sushi place on the mountain. After 4 days of heavy burgers,…read moresteaks and greasy food, we were really craving for an authentic Japanese dishes.
The restaurant has a retro vibe, the main room is small but with cool decorations. You don't really have a view of the mountain (there is only one small window, facing the street), but you won't need the view to kill time, i'm sure the food will grab all your attentions.
The services were really friendly and they all spoke in fluent english, and don't worry if you can't pronounce crazy german words - there is an english menu for you.
The food are not cheap, one nigiri is about 6 euro or more - and the rolls are about 15 euro+. However, i think it is acceptable in this kind of touristy place.
I am from Taiwan, and traveled to japan more than 20 times. To be honest, we were worried about the quality of the sushi at first since the european taste of Japanese food is really different than the real asian taste. But, the dishes were decent ! It was fusion and creative, but it doesn't lose the spirit and soul of authentic. The sashimi was sliced with the right angle with about 0.4 cm, and it was fresh. The rolls were fresh with a good twist of fusion sauce - you won't get tired of the taste even after 8 pieces.
In general, i would totally recommend for you if you are craving some sushi or asian fusion dishes - the only note is that this place is not cheap and it would probably cost you around 70- 90 euros to have a full meal.
