Check out the famous BBQ chain of Austin, Texas, Salt Lick Bar-B-Que, while waiting for your flight at the Austin-Bergstrom International Airport. The menu reads like a Southern comfort food Bible: beef, pork, sausage, and turkey. Choose from sandwiches or full plates—and don't forget the sides, which include baked beans, coleslaw, and potato salad. And like any good BBQ joint, it doesn't skimp on the sauce. What's better than the jealous looks you'll get from your seatmate on board? The fact that you can get a full tummy for around $20.
