we came here for the all you can eat, while we were waiting to take our flight back home. For $20, when you are hung over, it's fresh and it wasn't bad (except the vegetable roll.. is that mashed peas?)
I wouldn't most likely waste a 'dining opportunity' again being in vegas (and being I'm such a whore for hot wings etc) but it wasn't terrible, and it certainly was cheap (by vegas standards) and convenient.
If you are hungry, on the strip, and want sushi - it's better than some.
