Japango is one of my favourite sushi joints in Toronto. The sushi is fresh and their rice is superb. Some of my favourite rolls:
-dragon
-rainbow
I recommend getting an assortment of the sashimi as well. The seared sashimi is amazing!
The restaurant's very cramped, there are about 7 or 8 tables I believe. The service is top notch. If you're there during peak hours, your food will come within one or two minutes of ordering, and your entire meal will be done within half an hour! Guaranteed!
