In case people don't know, Nobu is the restaurant chain of a chef, Nobu Matsuhisa who has starred on that Food Channel show, "Iron Chef." He has brought the gourmet "New Japanese" cuisine to the world. This place is very expensive...but the taste is extraordinary. The Black Cod with miso melts in your mouth. Every dish is a work of culinary art. The service at the Las Vegas restaurant is excellent. They constantly make sure everything is clean, and ready, glasses filled, and your needs are met. The bill for 6 of us was $270 before tip, so this is costly, but not too over-priced. It is definitely an upper echelon restaurant. The Las Vegas venue is situated in the middle of the Hard Rock Hotel and is therefore several decibels too high. If you eat there frequently you are going to lose your hearing. That is why I give it 4 stars. I can imagine this restaurant outside of the Hard Rock Hotel will be more pleasant. If you're in your 20-40's you'll probably give it 5 stars.
