Came here for lunch when most of the Japanese restaurants closed for day time on New Year's Eve.
They offer sushi buffet for lunch and dinner with pretty good selections. However, we didn't choose their buffet since we wanted some sashimi and hamachi karma. The fish was fresh and they did give us huge sizes on the sashimi.
Overall, I think they are just an average level of Japanese restaurant, nothing has "wow"ed me but nothing bad.
This is about 8-10 miles away from Las Vegas strip - kind of far.
