I've eaten lunch here a few times and I have no major complaints.
As a lunch spot it's bang on what I usually look for - quick, tasty and cheap.
It has $4.95 lunch! Just when you think sushi lunch specials can't get any cheaper, they do here! They have a few options at that price range, I usually get the sushi combo with choice of 2 rolls (6 pieces per roll), miso soup and salad.
I also like that it's super clean and modern looking inside, unlike the typical Yonge St sketchy looking spots.
My verdict - nothing special but nothing to complain about either.
