We saw this one in New Jersey, near Carney’s Point. It’s a Silk City. It’s hard to tell precisely what it is, I don’t recall there being any signage on it. A large porch has been added, as has a handicapped ramp, which in conjunction with the roof addition, obscures the majority of the diner. There’s an open/closed sign in the front door and tables on the porch, so I can only assume its still a restaurant of some sort.
A view from the side. It looks like the roof addition does not actually cover the roof or protect the diner, it’s just for the porch. The diner may have been painted that red color at one point.
A different day, in the pouring rain
