El Rincon, a Mexican restaurant in Pflugerville that faced fallout earlier this year from a viral story claiming teeth were found in a barbacoa taco it served to a customer, has permanently closed its doors.

A sign posted this week on the front window of the restaurant at 200 E. Pecan St. says it has closed after a "tough year."

"With a heavy heart, we must close our business permanently," the sign reads. "We would like to thank our staff and customers for the business over the years."

In March, the restaurant received national attention when a customer posted online that she found teeth inside a barbacoa taco she ordered.

The story, first reported by San Antonio news station KENS5, got picked up by national news outlets and received hundreds of online comments.

On Yelp, the restaurant received an average three-star review.
