I went there some time ago with a huge party, and I guess that should explain the "blunt" style of the waitress. However, the sushi and the sashimi was SO GOOD that it made it all worthwhile.
By the way, if you go there, for the love of God, just try something called "MISSISSAUGA ROLL". This is the only place I found that serves this kind of roll, which has salmon and cream cheese and is deep fried. It's called "hot Philadelphia" in Brazil, and it's AWESOME.
I guess if you arrive too late you will wait for a bit... the place seemed crowded after a while.
