The fire started around 5 a.m. at Plank's Bier Garten on South High Street in German Village.

Firefighters were battling flames at a south Columbus bar and restaurant Wednesday morning.

The fire started around 5 a.m. at Plank's Bier Garten on South High Street in German Village. The Columbus Division of Fire was called to the scene at 5:17 a.m. Wednesday.

When firefighters arrived, they saw smoke pouring from the roof of the building. Firefighters say when they forced their way inside they encountered thick smoke on the first and second floor.

South High was closed in both directions at East Whittier Street due to the fire.

Shortly after the fire was put out, fire officials say they were able to locate the source in a second-floor utility room.

Investigators made a preliminary determination that the fire was accidental. They are looking at the oven pipe that may have gotten too hot and burned through the floor.

The business suffered severe smoke and water damage. One employee told 10TV Plank’s will make repairs but it's a difficult time considering it's the holidays. They are currently uncertain when the business will reopen.

The Plank family has been serving central Ohioans for three generations.

The family began working in the restaurant business in 1939. In 1960, Walter Plank's son. William Plank, purchased the building that is now Planks Bier Garten.
