It is hard to find good quality fish in Las Vegas being that we live in a desert and our nearest lake is radioactive. But Nobu manages to find some high quality and good tasting fish. So far this is the only Japanese restaurant in a Casino that I have actually liked.
The Bluefin toro Tartar was really fatty which I love and it was sitting in a wasabi sauce that was amazing. With the caviar on top it is one of the single best bites of food I have had.
If you go I would stick to the specialty items on the menu and not order the sushi. You can get near equal quality sushi for less money at other places and it will fill you up faster so you wont get to enjoy their menu as much. Also, the black cod with miso was sooooooo good. The fish melted in my mouth and didnt fall apart when I put a fork to it.
The Saki selection is small but the ones we tried were great.
The lack of 5 stars is due to the fact that we ordered Yellowtail Sashimi with Jalapeno was soaked in sauce and there was no resemblance of fish in the dish. Everything else we had we loved though.
