A popular Douglasville restaurant’s doors were closed Sunday after a fire ripped through the building and the roof collapsed.

Investigators were working Monday to determine the cause of the fire that burned down Kenny’s Home Cooking in the 5700 block of Fairburn Road, according to Channel 2 Action News.

Investigators said they believe the blaze started in the kitchen and spread to the dining room.

No one was injured in the fire, which started more than three hours after the last workers left the building around 6:30 p.m., an employee told the television station.
