I have been to a few sushi places in Toronto and Izakaya is by far the best in terms of quality for a great price.
Other places charge you over 20$ for all you can eat and you can grab a wicked deal at Izakaya for all you can eat at around 15$ or grab a bento box for under 10$.
The prices, quiet atmosphere, location and quality of the food makes it my favourite sushi restaurant.
I do think they should include endamame on the all you can eat menu.
Several vegetarian options.
