This is my go-to place for all-you-can-eat Japanese food in Willowdale.
The store is quite small and oddly shaped; its triangular shape means that the seats are often too close to anybody walking by. However, for a store space so close to Yonge and Finch and without its own parking lot, parking on Yonge Street is remarkably easy because this mall has mostly hair salons and health-product stores that close much earlier than dinnertime; I've gone to this place four times in three months and have never failed to find street parking. It's not free, though.
I like the food here; its hot food is especially good, sashimi pieces are large, and the menu has a great deal of variety. Service is a bit hit or miss; the staff is pleasant, but this restaurant appears to be a small, possibly family-run business so staff sometimes gets overwhelmed. You can see they make an effort, however. And the price is a good $2 to 3 lower than the other all-you-can-eat Japanese place around here, Sushi One.
