The blaze broke out near Pacific Coast Highway and Sweetwater Canyon Road around 11:30 a.m. By around 1:20 p.m., the second-alarm fire charred around 40 acres and was 20% contained, the Los Angeles County Fire Department said.
Flames were creeping uphill amid a light wind blowing from the southwest, but it was under control by 3 p.m., according to authorities.
"It was only about an hour that it was really scary....everybody's a little on edge but it was amazing how quickly the fire department got on top of it and knocked it down," said Jimmy Chavez, Duke's Restaurant manager.
Structures were not threatened.
The Los Angeles County Sheriff's Department's Lost Hills Station said on Twitter that Sweetwater Mesa Road was closed in the area due to the firefight. Firefighters were scheduled to be in place throughout the night to keep an eye on things.
