About Jack in the Box

Jack in the Box is an American fast-food restaurant founded by Robert O. Peterson in 1951 in San Diego, California, where it is still headquartered today. In total, the chain has 2,200 locations, primarily serving the West Coast of the United States. Food items include the Jumbo Jack, Sourdough Jack, and Ultimate Cheeseburger. The company also operates the Qdoba Mexican Grill chain. Robert O. Peterson already owned several successful restaurants when he opened Topsy's Drive-In at 6270 El Cajon Boulevard in San Diego in 1941. Several more Topsy's were opened and eventually renamed Oscar's (after Peterson's middle name), and by the late 1940s the Oscar's locations had developed a circus-like dcor featuring drawings of a starry-eyed clown. In 1951, Peterson opened a similar restaurant on the Pacific Coast Highway in Long Beach, with a giant clown's head atop the building.
