Listen to your server when she tells you to order appetizers.
The fluke sashimi in yuzu is fantastic. The bf still talks about it a year later and says it changed his understanding of what good fish is.
The rolls are totally forgettable and very small for what you pay. I honestly can't recall what else we ate there.
The service is great - everyone is a real sweetheart and our server had a wonderfully dry sense of humor. She also helped us stay within our budget (we tend to go WAY overboard when we do a la carte).
The sake was served at the perfect temperature.
Honestly, the three stars are because I think your money is better spent elsewhere in Vegas and because there's such a huge difference in quality/value in items on the menu. The sashimi was some of the best I've ever had, the rolls were some of the worst.
But the fluke was so good that the bf suggested going back just for that.
