A west Tulsa fast food restaurant was heavily damaged by a fire that broke out in an office late Tuesday night.
The Tulsa Fire Department says it got the call just before 10:30 p.m. at the Lot-A-Burger near 23rd and Southwest Boulevard.
When firefighters arrived, heavy smoke was pouring from the restaurant which was closed at the time.
Fire officials say the cause of the fire does not appear to be suspicious, but it remains under investigation.
No one was injured.
