Try dropping a group of 9 post-college kids into Vegas after some tiring travel and getting everyone to agree on food... thank goodness for Rock & Roll. It's not a long walk from the Strip and the AYCE sushi is much better than most things you'll regret buying in a mega-hotel-casino.
The rolls are well sized for sharing, but they do skew towards being overly embellished. Maybe I should just say that if you like your rolls drizzled with sauce and fried, come eat here. Edamame, miso soup, etc. are included in your AYCE meal, but why fill up on that?
The space itself is nice, and the service is friendly and prompt. I might have preferred Sushi Mon, but as a tourist, I'd definitely eat here again.
