Go for the 5 star food and setting, but be warned about the 3 star service.  

The menu lived up to all the high reviews posted by others.  Every dish was inventive and well done.  The salads were particularly noteworthy with the interesting and tasty use of local ingredients.  

The service was odd.  They were attentive, but amateurish.  It started with a request for a wine recommendation. The wine menu is heavy on Arizona wines, which we don't know anything about.  I don't think our waiter knew much more than us, and the wine he recommended was barely drinkable.  Next we asked a question about the tasting menu.  The answer took some time because, we were told, the waiter wasn't allowed to ask the chef directly and had to relay the question through an "expeditor." There were a lot of people helping us, but it was actually too much - it was distracting to have so many different people - and none of them seemed very well trained.  For example, we got our entree and asked about the purée on one plate.  Our waiter first guessed celery, and then said it might be cauliflower, and then someone else overheard the discussion and clarified that it was actually potato.
