I have been going to Ginza Finch and Ginza Thornhill for the past 12 years at least. This place has never let me down when it comes to sushi or non sushi items. The quality is fresh, the rolls are innovative. The product is not too overpriced and now due to their resounding success, the owners have renovated both locations and opened a third at Bay and Bloor and made all the spaces super funky and modern with fusica and white.
While you should go for the sushi, the ramen or soba noodle soups are great too.
