I've been coming to Japan sushi since I moved to the Annex a few years ago - of all of the sushi places on that strip between Bathurst and Spadina, it is up there with the best.
Extremely friendly service, fresh fish, good quality food (great tempura!) and an extensive and inexpensive lunch menu (7-10$ or so). The only reason my review didn't include a five star rating is that I have been brought the wrong order on two or three occasions - but they're always very gracious and offer to replace it, always bringing a little extra to apologize. Definitely recommend this place if you're looking for for good noms on the annex "sushi strip".
