The first-ever standalone Chick-fil-A, located at Greenbriar Mall in Atlanta, will close its doors Saturday after 56 years of service.

Printer-paper signs posted at either side of the location’s modern food court façade broke the news to patrons.

“Our last day of operations here at Chick-fil-A Greenbriar Mall will be Saturday,” the sign reads, concluding in classic fashion with, “It has been our pleasure to serve you!”

The location was the first to open as a standalone restaurant in 1967 after Chick-fil-A sandwiches had been licensed to more than 50 other restaurants and concession stands, including Waffle House. Through the 1970s and 1980s, Chick-fil-A expanded almost exclusively through shopping mall food courts.

Chick-fil-A now has nearly 3,000 locations in 48 states and overseas, and it has become one of the most profitable restaurant chains, generating average sales at freestanding locations of more than $8.5 million in 2022, according to QSR Magazine.

At the Greenbriar Mall location that started it all, Chick-fil-A still had the busiest counter in the food court.
