I thought that it was pretty good, but it was really expensive for the portions sizes that you got.
I got some of the generic sushi varieties because I didn't want to chance it before seeing a show, and I would have to say that I could have gotten the same (if not better) at a hole in the wall joint off the strip. It was average and the only difference was the plate it was served on.
I do not think that I will be going again unless it is for entertainment purposes on the strip.
