Place is new so you can expect that they are still working some kinks out. Thus the 4 stars.
Last time I was there, they're still in the process of getting their alcohol license. So no beer in the meantime.
Other than that, the food is really good. Their Yakitori is tasty and their appetizers have good prices and portions. And the place is in Summerlin too. If you want a good sit-down Japanese place, you got it here.
