Owensboro firefighters were called out just after 4 a.m. to one of the restaurant's pit rooms. Crews were able to contain the fire quickly.
The restaurant's owner says it started while workers were cooking bar-b-q.
"Everything's back to speed," said Ken Bosley. "It'll just take a little extra work to wipe everything down, get rid of the smoke."
"It's lucky that they keep somebody with it at all times to watch the pits," said Fire Chief Steve Mitchell, "exactly for this reason."
Fire officials say no one was injured.
