After 55 years of serving internationally renowned barbecue in Driftwood, the Salt Lick is honoring its cofounder with Thurman’s Old-Fashioned Burger at Austin Bergstrom International Airport. Thurman Roberts traveled across Texas for work and he loved getting burgers at little stands along the way. Thurman’s Signature Cheeseburger was modeled after his favorite burger and includes two 1/4lb. beef patties with secret seasoning with a slice of cheese in the middle.
