All Texas In-N-Out locations closed on Monday due to an issue with bad hamburger buns.
The locations closed after the company decided the buns did not meet the quality standards it demands, according to a letter posted on restaurant doors.
"There was and are no food safety concerns. We decided to close all of our Texas stores until we are confident that we can serve our normal high-quality bun. A new shipment of buns is on the way and we expect to reopen within the next 24 hours," the letter said.
The Waco location has remained closed on Tuesday.
According to KXAN, the company says the restaurants will reopen on Wednesday.
