The Bridgeton Grill is an incredibly in-tact early silk city.
It is the only diner I can remember seeing with a Silk City decal on its woodwork.
The kitchen addition off the right side has window and door profiles that remind me of an old lunch wagon. Probably just a coincidence.
Sadly this happened recently. http://www.nj.com/cumberland/index.ssf/2012/10/bridgeton_diner_devastated_in.html
