I was there with my girlfriend for dinner and it was a wonderful experience. The sushi is very well prepared with quality ingredients and the menu offers a wide choice. We enjoyed the "standard" rolls, and we definitely loved the "sushi bignè" (one-biters served on a spoon).
Our waiter, Andrea, was entertaining, professional and very caring (and he gave us a wonderful advice on the yummy nutella-maki dessert).
The following week, after a very long day, we decided to call for a delivery at home and we were not disappointed: same quality, punctual with the delivery, very well boxed.
I would say this is THE sushi place in Bolzano!
