Keller's Drive-In (Keller's Hamburgers) • 1950

Jack Keller learned the drive-in trade at Dallas' original Pig Stand before opening his own place on Harry Hines Boulevard in 1950, perfecting the formula with smiling carhops, cold beer served to your car, and the No. 5 Special—a double-meat burger on a poppy seed bun with grilled onions and house sauce. Bikers and classic car clubs still cruise in on weekends, turning the red-tabled parking lot into a time capsule where a burger, tots, and shake cost less than ten bucks.
