Yeah, I wasn't very impressed with this all you can eat sushi joint. I found it strange that 1 order of a maki roll was for only 2 pieces. What the what? I spotted a tray with pre-plated sashimi on it covered with saran wrap. So yes, it's quick and edible but even at $14.49 for lunch I still didn't think it was the worth the money and have eaten much better all you can eat sushi in my time. Also found it strange how limited the all you can eat menu was, but I suppose that makes sense if everything is pre-made... sure, it's busy so what you get is fairly fresh but personally I'd rather wait and get something that has been made to order. Also found that the nigiri and maki rolls fell apart very easily.
As a final warning, I'd suggest you stay away from the edamame, it looked pretty wilted, wasn't salted and was just plain bad. I couldn't finish it.
So if you couldn't tell by this review, I will not be returning to Kanda any time soon.
