Jack in the Box is an American fast-food restaurant founded in 1951 in San Diego, California, where it is still headquartered today.

A taco is a traditional Mexican dish composed of a rolled, folded, pliable maize tortilla filled with an edible substance. According to the Real Academia Española, the word taco originally meant (and still means) a plug (rolled paper used to plug a hole) or paper or cloth patch for musket balls. Care should be taken when using the word taco outside of Mexico, as the RAE lists 27 possible meanings for the word.
