I work right around the corner from Osaka Sushi (at Dundas West and Bloor) and I seriously order spicy maki set every time I eat here. The lunch special is only $12.95 and the rolls are HUGE. You get a fresh green salad with some yummy miso soup. I can say that I eat a lot and this one meal fills me up HALF WAY THROUGH. I usually have to go the rest of the day being hella stuffed but it doesn't matter cause their food is soo good!
I recommend calling in 10 minutes before if you're picking up. It's usually not too busy during lunch but just in case!
