Diners who showed up to Farm Burger in downtown Birmingham today were in for a disappointment. The restaurant, located in The Waites building at 707 Richard Arrington Jr. Blvd. South, has been closed since Sunday.

A sign posted on the window, expressing a warm “farewell” and “thank you” says April 7 was Farm Burger’s last day of business. The full sign says:

“Sunday, April 7, was the last day of business for Farm Burger’s Birmingham location at The Waites. Farm Burger is grateful to the community and local vendors who have supported its mission for nearly two years and plans to return to the Birmingham market in the near future.”

AL.com reached out to the restaurant’s PR team, who forwarded the same message via email.

Farm Burger’s closure didn’t seem to be common knowledge, despite being closed for nearly two days. Diners showing up a little after 5 p.m. for dinner were visibly shocked to learn the restaurant was closed. Some walked across the street to neighboring MOOYAH Burgers, Shakes, and Fries. Even some employees in neighboring businesses hadn’t noticed the sign announcing the closure.

The Georgia-based restaurant chain known for serving grass-fed beef hamburgers and using fresh produce from local farmers opened its Birmingham location in 2017.

The restaurant served craft beers from Birmingham’s breweries, including Good People Brewing Company and Trim Tab Brewing Co.

The Farm Burger on Richard Arrington Jr. Blvd. South was the chain’s second Alabama location. The first location is in Huntsville.

The original location in Decatur, Ga., has been featured on Food & Wine magazine’s list of the Best Burgers in the U.S.
