Taco Bell was founded by Glen Bell, an entrepreneur who first opened a hot dog stand called Bell's Drive-In in San Bernardino, California in 1948. Bell watched long lines of customers at a Mexican restaurant called the Mitla Cafe, located across the street, which became famous among residents for its hard-shelled tacos. Bell attempted to reverse-engineer the recipe, and eventually the owners allowed him to see how the tacos were made. He took what he had learned and opened a new stand in 1951. The name underwent several changes, from Taco-Tia through El Taco, before settling on Taco Bell.[from wikipedia]
