If you've never been to the Phoenix Sky Harbor airport, don't be alarmed - you aren't missing anything. Really.
On our most recent trip to Phoenix, we thought we'd see a lot of updates from our last visit but it still seems really outdated with very few restaurants to chose from. A lot of airports these days are getting facelifts and bringing in more trendy places to eat but not so much here. At least not in the Southwest Terminal.
I will say, I love the moving walkways though.
