3.5 stars, I'll round up.
Hikari is yet another of the many AYCE sushi places in town. It also has a teppanyaki section. The menu isn't that big for AYCE, but this is the first AYCE place I've been to in Vegas that offers sashimi on the AYCE menu. They were out of some items, which was a bummer given the pricier dinner price.
The food was decent, and service not bad. The interior decor is average.
