For all the things that the PHX airport doesn't have (style, walk-ability, comfort, etc), it always surprises me with little gems like this hidden down it's brown, dark and depressing corridors.
Cartel offers an alternative to Starbucks in a friendly and comforting package. Prices are about the same but the taste of the drink is just different enough to make you think you have found a whole new gold mine just waiting for the picking.
Next time you are awaiting your Southwest flight, make sure you visit Cartel for a refreshing beverage. All of this can be had before fighting with your fellow air travelers over spot A45.
