As others have said...this is airport food, and Sky Harbor isn't known for it's establishments in the terminal.
That said, these guys put a decent sandwich together, provided you don't let them overload it with lettuce and tomato. They have extra items (olives, etc) that aren't on the menu....so if you don't see it, ask.
Just a basic thin steak sandwich. The fries are ok, but they lose their temp quick.
They overcharge a bit for their drinks, which are just 20 oz bottles....but I think their fountain machine appeared to be out.
Not the cleanest looking place....but when you need something to eat at 9 pm on a Sat night with a flight in 30 min, you work with what's available.
