Went there with family (4) a couple of days ago as we had a $10 off coupon (did not notice it had expired - bummer). Most tables were empty but service was still quite slow. None of the staff seemed to be happy to see us. The restaurant is clean, though utilitarian.
We ordered a sushi party tray as none of us was very hungry for the "all you can eat" deal. The sushi was very mediocre and not much better than what you can get from an asian supermarket. I usually give restaurants at least 2 visits before writing them off, just in case they have a bad first visit. So I will update this review when I visit the second time but they really need to do better.
