Came here on my last trip to Vegas, the rolls are pretty good, tasted pretty fresh.
Our server was great too, we ordered a roll and she told us we could get it but in her opinion it was not that good, and she suggested another roll that had a lot of the same ingredients on it, and she was right it was really good. We asked her for one more suggestion a little later and that was good too. It felt like she really cared and was not just working for a tip.
The location is great too, it's at the Fashion Show Mall, which is right next to Treasure Island.
