Ambiance was amazing, service was great and food was good. I'm not convinced the food is worth the prices they charge but what the food lacks is definitely made up for by the beautiful surroundings. Having said that, I would certainly go back to enjoy drinks and apps in the lounge and relish in the atmosphere and listen to the live music. Would probably skip out on dinner though unless someone else was footing the bill. They have live music seven nights a week in the lounge but the guy who performs on Tuesdays really blew me away. Acoustic guitar combined with a superb voice. His version of Piano Man on the guitar was exceptional.
As others mentioned, you have to walk through the smoke filled, noisy "ching ching ching ching" casino to get to the Orange Sky elevators but once you're up there you forget about all the casino happenings below you. And, the resort should really do a better job marketing this great spot. It doesn't even mention on their site that they have live music and to me that was the highlight. One more thing, I would probably wait a few (or more) months before going as they are still in construction clean-up mode surrounding the resort. Once the desert is free of construction debris and returned to it's natural desert habitat the views will be even better.
