The Marin Independent Journal reports (http://bit.ly/1dgDs5N) that the company is installing a pair of log cabins from the late 1800s to serve as dining rooms.
The cabins were salvaged from ranches in Montana by a Marin County contractor and sold to the owner of an architectural firm helping to refurbish Twitter's headquarters.
They should be in place within a few weeks. The plan is to build booths inside them for company employees to sit in while they eat.
