If you are looking at a connecting flight in Arizona and have your choice of Tucson International or Phoenix Sky Harbor, Phoenix is the larger and more luxurious sky port. They have an excellent website which can make it easy to find some food to your liking while here. I had the enjoyment of getting stuck here for about 6 hours but that had to do with Southwest and not this airport so I suppose that can be documented in another review...
One thing that is nice is that you have free wi-fi here. Every airport should have free wi-fi, come on... This is the 21st century.
Have never had much of an issue with security here either, it has always been pretty fast an efficient. It ain't LAX. :)
