Japanese owners and friendly staff with surprisingly slow service atop the Alsterhaus department store.
Atmosphere is a touch sterile, perhaps too many bright lights in a sea of unadorned tables, or maybe way too much space for what is at hand, so I wouldn't necessarily bring a date or choose this place for a special occasion yet otherwise all ok.
Ordered nothing but sashimi to see what the place was about. And the fish is fine yet not great, though perhaps good enough by German sushi standards? I give the restaurant 3 1/2 stars but as that is not an option I normally would give it 4 but taking the high price into consideration I rank it as 3 for being so-so value for money.
Better, and certainly the same, can be found elsewhere for less.
Overall, the energy feels low, verging on sad for a restaurant considered a good one, though this could just be me, and note -- the staff is friendly! I don't understand what is happening here nor the high ratings from other reviewers.
With a range of other options to eat atop the Alsterhaus I would consider something else in the area unless you are bent on sushi.
