A very underrated taqueria. Not as gringo friendly as some of the Valencia Taquerias (or even Cancun), this place churns out massive, fantastic burritos. The carne asada is a little greasier here (you will most likely have grease running down your arm on the final couple of bites) but the size and the flavor cannot be beat. The only reason I can't give it five stars is that 17th and Mission just sucks - it's one of the worst blocks in SF.
