I went here for dinner about 3 weeks ago based on a suggestion by a friend who is a regular here.
Ambience-busy, but not cramped, casual dining atmosphere
Quality of Food-Decent, but I've had better Japanese food elsewhere. I guess people come here for the value
Quantity-Good decent portions
Value-Good value for the portion you get.
Service- fast and good.
Summary-
I would skip this restaurant if you're looking for very good Japanese food. If you're looking for cheap yet decent Japanese food, this may do, but I would sooner go to Ho Su on Queen West.
