I went to Ginza for lunch on a Wednesday with my partner and we ate from the buffet menu. The options were limited but the food was good. My partner was in fact extremely pleased, repeating how much the food was better than most other sushi buffets in Montreal (the best affordable buffet we've been to is still in Toronto however). The service was a bit on the slow-side but it was still acceptable. As a vegetarian, I can say that the veggie options were extremely few, even compared to other sushi buffets, but the ones they served were good. I recommend the mushroom and tofu tempura.
