Why locals love it
It's very central because it is in Hauptbahnhof area.
The ingredients are of a very high quality and your meal is freshly prepared and cooked in front of your eyes at the grill. A lot of business people go there around lunch time.
Why you should visit it
It's very communicative to sit around the hot plate where your food is cooked directly in front of your eyes. Some of the menues/dishes you won't find at the sushi store or asia take-away around the corner.
It's one of the best restaurants for high-class Japanese food.
It's a bit expensive, so better try it for special occasions. If you want to test it first: the lunch menu is strongly recommended.
