A popular set of family-owned burger restaurants in Pensacola has closed down.

Owners of the Burger Factory on North 9th Avenue and Navy Boulevard announced Monday morning on Facebook that the fast-casual burger restaurants are closed permanently.

"We want to thank everyone who has supported us the last 4 years. But (due) to many reasons we have decided to close up shop and put our focus on other things," the post read. "It has been a great ride and thanks again for making our dream a reality."

The Burger Factory specialized in gourmet burgers with unique ingredient combinations, sandwiches and hefty salads. Just a month prior in September, the restaurant celebrated its four-year anniversary at 6907 N. Ninth Ave.

The social media post didn't specify if both Burger Factory locations are closed, but Google lists the 314 S. Navy Blvd. Burger Factory as "permanently closed" as well.

The husband-and-wife owners could not be reached for comment Tuesday morning.

The Burger Factory building on Ninth — along with the entire shopping center it sits in — is owned by Validus Group Properties. Validus didn't immediately respond to phone and email requests for comment.
