I had an enjoyable dinner here during a trip to Vegas for CES. The menu contains the standard Morimoto fare (modern Japanese/fusion fare), and is essentially a clone of the Napa/NYC locations. The rock shrimp tempura was solid, and the selection of nigiri I ordered was fairly high-quality as well, with fresh cuts although nothing out of the ordinary.
Service was very friendly and attentive, and a wide variety of wines, beers, sakes, and cocktails are on offer as well. However, I did find myself wishing for a greater variety of sushi, and I was somewhat disappointed that omakase was not available. That being said, this place is definitely a decent option if you're looking for decent-quality sushi or upscale Japanese fare.
