You would normally need to go all the way out to Gilbert to enjoy Joe's. Now, you have the benefit of enjoying one of the tastiest bbq joints right at the airport, and not pay inflated airport prices (not sure how they pulled that off). The seating is a bit exposed, but my expectations of ambience wasn't high for the airport too begin with.
The bar seating area has electric outlets for charging your phone. Definite plus for the airport.
