"It took a feat of engineering to produce legal and traditional barbacoa inside of a U.S. restaurant. Former engineer and barbacoa master Paco Perez has done just that with his own oven design to simulate the conditions in an underground pit. Pit-roasted tender lamb cuts, pancita, and lamb skulls are served with corn tortillas, papalo (wild greens), and green and red salsas for making tacos, just like back in Texcoco at this large restaurant in Commerce." - Bill Esparza
