Good restaurant options outside security (think, Paradise Bakery!) and inside security. Every where you look is an eager and friendly volunteer standing by to help you. I stopped at the volunteer desk to ask about restaurants inside security, and he had an up-to-date map of all the food options, very helpful.
Security is always... ummm.... "enthusiastic." When I went through last week, they were still requiring people to take out their liquids/gels in their plastic bag for screening, which I haven't seen for a while. Allow an extra 30 min for PHX security!The lines can be very long, and slow.
It's a long walk from security to some of the gates, but they have people-movers which help a lot. (Just don't decide you really wanted to eat in the terminal you just left!)
Free WiFi--yeah!
