There is an interesting discussion taking place on the LA board regarding "SF style burritos." Check it out. And since we're on the subject: my sister is moving to within a block or two of the Mission very shortly (by end of the month). Since we will no doubt pay her various visits, what are your suggestions for "SF style burritos" in the Mission (or tacos, for that matter....I actually like tacos al pastor better than burritos.) I know its probably been discussed a hundred times before, but what are your recent favorites?
