I will start with my only complaint: the service at Kaizen is very slow. Plan to spent awhile sitting at your table waiting for food.
That said, the food is excellent. I have always greatly enjoyed the sushi I had there. I decided that my college graduation gift to myself would be a dinner of Kobe beef - Kaizen was the only restaurant we could find with it on the menu (we didn't complain, we already were a fan of the restaurant). It was excellent. The dessert menu isn't too exciting.
