As a sushi lover avoid this place by all means. The cut rolls are expensive and definitely regrettable. The rolls were sloppily put together, small, plus they only gave you eight rolls considering the average price was about $17. Also there sashimi was semi chewy. Great sashimi should melt in your mouth!
Granted most sushi bars are expensive in Las Vegas...But I have had better sushi for the same price at restaurants on the strip.
I would pass if I were you. Go to Shibuya at the MGM.
