Recently Taqueria La Cumbre on Valencia got a fire engine red paint job. But far more bold than the color scheme is the claim painted on the building: “Birthplace of the Mission Style Burrito.”
As with any such claim, it’s a hotly contested one. As Wikipedia notes it’s not clear if Mission-style burritos were invented in San Francisco at all. Further adding to the confusion, La Cumbre’s “birthplace” claim refers to the building rather than La Cumbre because the burritos were originally sold there when a meat market occupied the space.
The truth is out there, but until someone invents a time machine we’ll never know for certain where Mission-style burritos came from. If anyone reading this happens to have a time machine and wants to research this, please give me a call — especially if it’s around lunch time.
