Update 10:54 a.m.: Service has been fully restored to all lines according to the San Francisco Municipal Transportation Authority.

A fire in West Portal that was reported at 4:40 a.m. is now contained, but inbound K-Ingleside and M-Ocean View Muni lines at West Portal have been blocked. Shuttles for downtown commuters are departing from St. Francis Circle to ease delays.

The fire started at 1 West Portal Ave. in the Squat and Gobble restaurant. It was reported as a four-alarm fire, according to San Francisco Fire Department spokeswoman Mindy Talmadge.

The fire began in the attic space of the restaurant. The building became unstable as fire crews got to the origin of the fire. At 6:24 a.m. firefighters changed their offensive approach to defensive.

Two firefighters reported minor injuries including smoke inhalation and a laceration.

“The fire is pretty much under control,” Talmadge said.

According to Talmadge the fire was contained at 8:09 a.m. and extended to other businesses including a dental office and a bar.

The cause of the fire is still unknown.

“There’s nothing to determine if it’s suspicious,” Talmadge said.

A bus bridge has been set up at St. Francis Circle for downtown departures.
