El Primo

The migas taco here comes built with deli ham by default.4 Andrea Valdez's is the al pastor, shredded, saucy, slightly messy pork, served on thin double corn tortillas.1

Why go

The trailer parked on South First nearly ten years before Texas Monthly came by in 2014, and Valdez's photograph of the queue is still the best description of who eats here: some paint-splattered construction workers shared the sole picnic table with a bearded hipster type strumming a Les Paul guitar while he waited.1 Brion scored it 7.6 and the reason is breakfast, which he calls some of the best in Austin.4 The honest caveat comes from Valdez, and it is a buying instruction: The lengthy menu may sometimes overreach, but most tacos are simply and skillfully executed.1 You watch the cooks work the griddle while you wait.4

Order this / avoid

  • The migas taco, ham included, and the homemade chorizo and egg.4
  • Al pastor, with the lime, the cilantro and the coarse raw onion it comes with.1
  • Lengua, which Valdez found tender and meaty and best punched up with a splash of the chile de árbol–garlic salsa.1
  • Or the tripas, which is the Chronicle's lunch pick alongside the pastor and the barbacoa.2
  • Avoid going deep into the menu. Gringas, sincronizadas and veggie tacos are all on the board, and I haven't found a critic who has written about any of them.31
  • Afterwards: Once Over Coffee Bar is directly behind the trailer.4

What locals & experts say

  • The Infatuation Austin, Raphael Brion, 7.6 out of 10: Order the very good migas tacos, which by default are made with deli ham – something you don't see very often.4
  • Andrea Valdez put it on Texas Monthly's sixteen great Austin tacos in 2014, with the pastor at US$2.25: you'd be hard-pressed to find a better value in this area. That price is from 2014.1
  • The Austin Chronicle calls the truck the case for the whole city's breakfast taco: it is exhibit A to why the breakfast taco is so huge in Austin.2

Good to know

  • Expect a line. Brion's framing is that queueing for food is a sport in Austin and this is one of the queues with a reason.4
  • There is one picnic table, and a lot of people eat standing beside it.1
  • It is a trailer, so the city's restaurant inspections do not cover it. There is no score to give you.5

Verdict

should-visit — A trailer that has been on South First for over a decade making what The Infatuation calls some of the best breakfast tacos in Austin, scored 7.6. The order is migas with deli ham in it and a chorizo made in house. Cheap, quick, a line, picnic tables, coffee directly behind it. Off the top rung because it is one meal of the day done very well rather than a full kitchen, and because no public inspection score exists for a mobile vendor.

Order

  • Migas tacos, which come made with deli ham by default
  • Homemade chorizo and egg taco
  • Al pastor, shredded and saucy on thin double corn tortillas with lime, cilantro and raw onion
  • Lengua, with the chile de arbol and garlic salsa on it
  • Tripas, barbacoa and the rest of the lunch board
