I've been in a lot of airports and PHX isn't too shabby. With high windows i was able to watch the sunset and planes taking off and landing. There are fairly good food options. I myself opted for California Pizza Kitchen and found the ~$11 personal pizza to be decent. Too bad the employees weren't as enjoyable as my pizza! I've never seen people move in such slow motion. The cheese topping on my pizza was probably drying up each passing moment!
Free Wifi. Woo! That's a big thing if your overlay is at an airport. Other than people watching and eating expensive airport food, i like to browse the internet when i can!
