This is my go-to sushi place when I'm in the area.
The sushi is really fresh and the staff are friendly and polite. There aren't any remarkable sushi dishes, but you're bound to get tasty sushi, so you can't really go wrong. Their signature rolls are all pretty good, though I would recommend the Queen's Quay above the other ones. Their other rolls are all pretty good. If you can't decide, then I'll have to recommend their Rainbow roll since you get a good idea of how fresh their cuts of fish are. They also make damn good unagi hand rolls.
They are better than the ordinary fare, so this place is good when you're craving sushi, and you know you can't get into Mi-Ne sushi because it's too damn small and crowded. It's not out of this world amazing sushi, but it's good, and really convenient since it's usually not very busy.
4 to 5 stars for the pleasant service, and an honest 3.5 stars for food, but it gets rounded up to 4 since we're in Toronto and you really can't get amazing sushi here.
