Buen Sabor is the best taqueria in the Mission. I have been going here for three years and never walked away unhappy. The Al pastor and grilled chicken are excellent. If you like to mix it up, I suggest the Especial with black beans, pinto beans, al pastor, and chicken. Don't be afraid to order the nachos, topped with some of the Mission's best refried beans. An added bonus is the friendly staff.
