There were a bunch of 1950s-era storefronts in Central Square in Cambridge, MA, that lasted well into the 1990s. Central Square ended up being renovated in the late 1990s. In the early 90s, I used to go to a lunch counter there that was a virtual time capsule: Checkered tile, formica countertop, spinning bar stools, ceiling fans. I would order a grilled cheese sandwich with potato chips, pickle, and a coke. The whole thing cost $1.99. It was like stepping back in time. I believe this place was a casualty of the renovations but perhaps StereoJack or someone from that area can confirm.
