Teeny mom-and-pop kind of place. Just one sushi chef, just one waitress. I go in about once a week and I'm never disappointed. Great deal on the lunch special, though oddly it's never quite as tasty as the dinners, which are the best I've had in Toronto (granted, I haven't eaten at any of the high-end sushi places here).
Definitely the best sushi in Bloor West Village. I've lived in the neighborhood for over a year and tried them all!
