If I am craving sushi for lunch, Sushi on Bloor is my go-to restaurant. At 6.99 for their lunch special, it's hard to say no!
They offer hot meals, bento boxes and sushi combos. I always order the S2 sushi combo - it comes with dynamite and avocado roll. Every lunch special comes with salad and miso soup so it ends up becoming quite filling.
Back in the day I used to love Sushi on Bloor, day and night, but now I think it's simply a good cheap spot for your sushi craving at lunch.
