I have to caveat this review by saying that I was upgraded to a corner suite. I was at a conference at Caesars and the Nobu Hotel was only a few dollars more so I decided why not? Yes the location of the entrance is not intuitive, but when I asked the roulette dealer where it was he sure knew and was able to give good directions.
Coming here on a business trip this hotel was ideal. Much quieter than most. Better bath products. Very comfortable bed. While the "business floor" just seems to be 2 computers by the elevators, having self-serve, good-tasting coffee in the morning is a huge plus. Also loved the steam shower but I think it's not standard in all rooms. And given that it's just one tower, never a long walk to your room from the elevator.
I've stayed in virtually every casino hotel and in Vegas and would say that Nobu is up there with my favorites. I'd put it on par with the Wynn/Encore, the design is more subdued but still nice IMO
