Police released surveillance video of one break-in showing the suspects force their way in to one restaurant by removing the glass in the front door.
They are seen rifling through a cash register, though it's unclear how much cash was stolen, and removing a few items of merchandise from a shelf before leaving.
Police released video and a description of the suspects on Twitter.
They were driving a beige four-door sedan, possibly a Nissan Altima.
Anyone with information is asked to call Los Angeles Police Department detectives at (310)444-1524.
