As I told someone else, I found a corporate listing for that restaurant in 1985 but it was at 7 Upjohn St which would put it at JM. The place I’m thinking was right on South River Road right at the highway underpass.

I did find old matchbooks online too for both restaurants and Bedford Marketplace matchbook says “Jordan Marsh Mall” and the one for “Quackers” says Bedford Exit off 293. So helpful. Lol
