ATLANTA (AP) — A fire that damaged a restaurant in Atlanta's Buckhead neighborhood is under investigation.

Atlanta fire spokeswoman Janet Ward told local media that a firefighter was injured while responding to a blaze Sunday morning at the OK Cafe. The cause of the fire is unclear and no additional injuries have been reported.

Melissa Roberts, a server at the restaurant, says employees tried dousing the fire with extinguishers before ushering customers out of the building and waiting for fire fighters to arrive on the scene.
