OMG! I haven't had authentic barbacoa taco's like these since I was a kid growing up in Houston, TX, south side. It brought back memories when I remember on Sunday mornings my dad would get a basket of barbacoa and corn tortillas from the local Mercado. So tender and flavorful. These are authentic Mexican street tacos. If you're in the area, you should stop and have two, or three, or four. I think I stopped at four?
