In the context for what this place is, I think it is pretty good.
I never expected this place to be high end with chefs trained in Japan by highly-regarded sushi masters working in Michelin-star restaurants or having competed in the Iron Chef.
What I expect is a place with fair prices ($9-$15), tastes like what it says it is on the menu and won't make you sick because they get a decent turnover of customers. And that's what I get.
I usually go there for their lunch specials and always finish my meal with my stomach fulfilled. The quality and taste aren't going to blow away the competition but they offer their dishes at a great value in terms of price and quantity. The food is fresh and pretty good so I always feel like my money was well-spent. In addition, their menu is quite extensive and probably offer more variety than the other sushi places nearby.
Yes, they do have Korean items on the menu but offering dishes that are non-Japanese seem to be par for the course for mid-range sushi restaurants in the GTA.
The service is pretty good and you won't be waiting too long as you place your order. They are pretty efficient. So if you're in the area, feel like sushi and not sure which one to try, you can't go wrong here.
