Rock n' Roll Sushi was ok. It was close to our hotel on the strip, so a group of us ventured over for dinner one night.
All you can eat (AYCE) sushi for $25 a person is definitely a good deal. You can order up to 3 rounds, but must eat all pieces or they'll charge you for whatever is left over. They have a ton of options on the AYCE menu, from sushi to rolls to dessert. The sushi and rolls were ok, not bad, but definitely not the best I've even had. What do you expect for $25?
As we ordered a variety of rolls, I found that all of them had fake crab salad inside. They must use it as a filler. The fried rolls are interesting, such as the sexy girl. Worth trying one! Also, we were not a fan of the baked rolls...warm sushi rolls = weird.
