I'm not a fan of most US airports. Unlike many (DIA, I'm looking at you) it's well maintained. All the faucets in the bathroom are functional and the gates I've been at are well maintained. It's fairly easy to get around. On a recent flight, we had two gate changes from the A concourse to the B concourse, and back again. At some airports, this would have taken forever, but it really wasn't a big deal here.
I never eat at airports, but there seemed to be a decent selection of places to get food, and most were busy. I'm going to try to use PHX as my hub airport, instead of DIA, as it's far more user friendly.
