"This popular Mexican-food mainstay in the heart of San Francisco 's Mission District is one of two places in the city that claim to have invented the Mission-style burrito (the other is El Faro): a hefty, elephant-leg-size wrap distinguished from other burritos by its size and the inclusion of rice and other ingredients. The restaurant was first opened as a meat market in 1967 by Mexican immigrants Raul and Michaela Duran, who are said to have served their first burrito in 1969 after noticingthat local workers needed a substantial yet portable meal. The Mission Burrito was born, containing most of the food groups: protein, vegetables, dairy, and grains. The Durans converted their meat market into a full-time restaurant in 1972. Taqueria la Cumbre offers a full menu of Mexican food, all made fresh. Theburritos are made assembly-linestyle. (Fun fact: When the Durans first came to San Francisco, they hired a high school kid to make flour tortillasbefore school. The kid, Jorge Santana, would go on to be a popular musician, like his brother Carlos.)"
