Great introduction to beef offal tacos, written by TheOffalo!!!
Pretty cool, since some of us like offal (http://chowhound.chow.com/topics/987665), and most of us like tacos (http://chowhound.chow.com/topics/903985), AND Tacolandia is coming up (http://chowhound.chow.com/topics/1006292)!
Any other offal taco vendor recommendations (beef or otherwise)? I know next to nothing about LA area tacos/ vendors, but I am a big fan of cabeza and lengua.
