If you're hungry at the Phoenix Airport, just take one piece of advice. Eat something on the "freedom" side of the security checkpoint. Once you get past security, every food source is packed and seats at which to enjoy your marked up food are far and few between.
Having learned this the hard way in the past, I grabbed a sandwich at the "To Go" part of Chelsea's Kitchen. Had "The Commuter," which consists of eggs, bacon, tomato and mayo on an English muffin. It also includes a tasty side of fresh fruit.
A kind woman took my order with a smile and forewarned me it would be about a 10 minute wait because the kitchen was backed up. Okay so it was a bit longer than 10 minutes. It happens.
Sandwich was good. Fruit was good. All perfect before boarding a flight...where you get to eat whatever you can find on the floor.
I've read good things about the sit-down part of the restaurant so I plan to try that on the next trip.
