Been putting this off, so now seems like as good a time as any. The stretch of York Blvd. between Eagle Rock and Figueroa has about 17 taco stands and Mexican restaurants, and I'm in the process of surveying them. Here's just a quick, innaccurate and disjointed sampling (due to poor memory of specifics like names and addresses):
Pretty good, dirt-cheap tacos. Little tiny ones. I had 1 carne asada and 1 carnitas, which didn't go along way towards filling me up, but only ran me a buck a piece. So, not spectacular, but quite good, and appropriately greasy. They had that good, hot salsa that you can only seem to find at taco stands.
This is the Yucatan place a block west of El Arco De Iris. Has a painting of a ziggurat out front. Anyway, I had a pork dish, roast pork marinated in citrus juices. They went a little overboard with the marination process, tasted more like oranges than pigs. Still, I'm planning on going back to try the other pork specialty there, cochinita pibil (?I'm sure I mangled that).
El Huarace Azteca:
This place serves a fantastic pork dish. Chunks of roasted pork in a salsa/stew. The pork is perfect--tender, fatty, crisp on the edges. Might be some of the best pork in LA.
Which isn't actually on York Blvd, but down Figueroa a bit in Highland Park. This is a Jonathan Gold reccomendation, and I went by his word and ordered Carne Adobado. Amazing. Very well-cooked pork with a robust, smoky flavor. There's a strange salsa at the table--deep red and very oily--that the meat can succesfully stand up to. I tried it in tortillas, with and without the beans and rice, but ultimately decided that it was just too good to eat any way except by itself, with just the onions and cilantro and a bit of salsa.
