One of the best purveyors of burritos in the Mission (which is saying something), Taqueria Cancun doles out superb burritos, tacos, and tortas. It's hard to choose between tacos and burritos, and while you definitely don't want to miss the carne asada or carnitas burrito, you don't want to pass on the al pastor super tacos either. They're packed with so much pork, pineapple, avocado, and other tasty goodness that they're basically mini burritos. The casual spot is jam-packed for both lunch and late-night eats (it's open until 1am on weekdays, 2am on weekends).
