I went to a location in LA and loved the experience. Great food and great atmosphere.
I've been to the one here at the SLS a few times and I'm never disappointed. The service is good, all the employees are friendly. And the food is still great. I don't like how the restaurant is open to the casino...it's not great smelling cigars and cigarettes while eating sushi. But what can you do.
The summer menu is also an amazing deal. I was stuffed by the time dessert came.
Overall, a great place to eat and take friends before a fun night out.
