Whenever I'm in the area, I always consider stopping by Mi'hito for a sushi burrito. Of all the places I've tried, I must say this Mi'hito makes it the best for my taste. Very fresh and tasty, lots of delicious toppings, and fast and friendly service.
You get a nice box to house your burrito so it stays intact while you transport it so it's great for those who study in the area.
Try the sweet tofu in your burrito. You won't regret it!
They also have a location in Mississauga, which is where I first discovered them. It's great they have this location near Ryerson as well.
