Traffic moves at an antelope’s pace on National Avenue, so it’s easy to unknowingly whiz by El Comedor. Advice: Keep your eyes peeled for a corner building with a bright-red threshold, then head inside and place your order immediately for crispy, succulent shreds of pork (a.k.a., al pastor). The meat is sweetened with tiny chunks of pineapple. Ask for cilantro and onion on top, and be liberal with the fresh lime! Look for El Comedor taco truck on South 13th and Hayes.
