Fast food has changed enormously over the decades, from early roadside stands to the drive-thru restaurants Americans know today. These wild fast-food facts include accidental inventions, bizarre publicity stunts, giant desserts, and menu items that almost never made it past the testing stage. The result was hardly close: McDonald’s says Groen sold 350 fish sandwiches while only six Hula Burgers sold. Taco Bell’s history says his earliest restaurant sold hamburgers and hot dogs, and other official Taco Bell material traces Bell’s first hamburger operation to 1948. He later opened Taco Tia in 1954, where tacos cost 19 cents, before launching the first Taco Bell in Downey, California, in 1962.
