This place is over-priced and over-rated.  You are paying for the ambience.  Service was excellent.  i had the sashimi combo and spicy tuna roll.  Two things that are easily comparable between restaurants.  Tuna was overly dyed dark red and the yellow tail was the toughest I've ever eaten.  However, the spicy tuna roll was a generous serving.  On top of the disappointment of my dining, I started experiencing food poisoning symptoms a few hours later. Sushiwa put a damper on my plans the whole next day.  Too bad Vegas has no exceptions on their ticket refund policy.
