Mr. Andrew Hall asked me if I knew where to get the best tacos in LA. Answer: No. But my excellent friend Karen Ahn does (she lives in LA and she knows everything: just look). I emailed her, and this is what she said:
My personal favorite taco place is Guisado's, which is right by my house. It is the tits. The tortillas are really hand-made. They do braises instead of the carne asada, al pastor, most of us non-Latinos are used to.
