The Western Sizzlin in Athens is closed Friday as workers assess the damage caused by an overnight fire.

The Athens Fire Department responded with three trucks to the restaurant on Decatur Pike at 12:57 Friday morning.

The fire captain told Channel 3 they found heavy smoke at the back of the restaurant and that it likely started inside the steakhouse.

The fire took 3.5 hours to get under control and completely out. The captain said there's "significant damage."

The Western Sizzlin will be closed for days, if not weeks, the captain said.

The cause is still under investigation.
