I have been here quite a few times already. They are awesome. Food is delicious - my favourite dishes are the salmon pressed sushi and the torched salmon sushi. They are the best - comparable to kaka sushi but at a lower price per person! The only thing is that sometimes they forget your order or if you order the same dish multiple times, they wont bring it all out for you. But that happens at every all you can eat restaurants.
All in all - hands down the best all you can eat sushi restaurant in the Markham/Richmond hill/Scarborough/north York area
