At least the US Airways terminal (which might be the whole airport, i'm not sure) is awesome. It is bright with real sunlight when possible with large windows and wonderful little rocking chairs to hang out on.
They have a Chili's there right in the middle which is always a favorite with me, especially at the end of a long trip. Who can say no to chips and salsa? AND a beer? I didn't think so.
It is super easy to get around the airport and while it is a spread out, it goes pretty quick. I think they have free wi-fi too, and pretty good shopping if you left something at home.
