We've been going to Kisoya on Dundas for years and we've never been unhappy with the service or the food. They have Bento dinners, full Sushi, Sashimi (of course) and Teriyaki meals (beef, chicken & salmon). We also like the un-ordered extra appetizers that appear before our meal.
5084 Dundas St. W. (in between Islington & Kipling, north side of street)
sushi to go down on queensway is nice and a little more low key that kaji.
I would highly recommend a trip to spoon and fork in the plaza at kipling and queensway. The sushi is pretty good, creative, and lunch is i think 1399 all you can eat. includes thai as well, bbq, soups, salads, sushi, and normal thai dishes.
Very fun atmosphere, would be fun for a 5 yr old I think, lots of opportunity to try. My 3 yr old enjoys it.
The sushi place on dundas near apache burger, besides li's oriental (formerly holeechow) is pretty good too, and not upitty.
