My husband took me to Compass in '09 for my birthday. It was a wonderful surprise because he had been telling me about this resturant since we moved to Arizona.
The only bad part of the experience that I had was the elevator. The way you get quickly taken to the top and quickly dropped to the bottom floor of the hotel caused my ears to pop on both our arrival and our depature from the resturant but other then that the food was great and we enjoyed the view of Arizona. We also had a very friendly waiter who made the experience wonderful too.
If your looking for something romantic and don't mind heights this is a great date night activity.
