Operating outside of a Food 4 Less in North Hills, San Marcos is a taco truck serving fantastic beef birria tacos that people wait in line for hours to eat. Open only until 3pm every day, these are the kind of cheesy, greasy tacos ideal for those foggy Sunday mornings when you need something to soak up the regret from last night. We usually order a few regular tacos, one taco dorado (crunchy shell), and a giant queso-taco for the grand finale. That said, whatever you decide to do, make sure to get a consomé as well - it’s one of the best versions in town and perfect for dipping your tacos into. Cash only.
