Looks like teeth? Could be teeth!
A woman in San Antonio ordered a taco from El Rincon Mexican Restaurant in Pflugerville, Texas and what was supposed to be barbacoa meat, sure turned out to what looked like teeth!
Can't see it that well? Let's take a closer look.
However, according to the meat vendor for the restaurant, they say it is "beef lips" (that doesn't sound too appetizing either LOL). Although this part of the cow is not usually associated with barbacoa, it is edible and approved for consumption.
