Unfortunately I spend my fair share of time down concourse A of Sky Harbor's Terminal 4. Fortunately this Olive & Ivy location opens early, closes late, has good food, and seems to hire friendly, kind, caring people. I've been here multiple times and have never had a negative experience. Now folks will complain about the prices but it's an airport restaurant so you must have reasonable expectations. Average panini will run you ten bucks and a side is a couple of bucks.
