I have been to the Summerlin location a number of times. The food is average to above average, depending on what you order.
The Tempura was greasy and heavy. I was doubtful whether they used tempura batter..
The rest of the food was good; Hibachi Chicken, Chicken Fried Rice and the sesame dressing on the salad.
The hostess who could be the owner allows the front of the house to get out of control. There is no rhyme or reason to how you get seated. It's very frustrating especially on a Friday night. We almost left a couple of times before being seated.
There are many options for sushi so we may be back, we may not.
