Then there's the Trolley Car Grill in Castroville CA. When I worked in the area an extraordinary number of years ago, it was quite recognizable as a trolley car, with a hole cut in back for a barbeque pit, kitchen, and grungy restrooms. Good ribs and chili, but kind of a dive otherwise. Amazingly, it seems to still be there and has been spruced up for the modern crowd.
