The thread on lunch counter food prompted me to think about retro food in general. And what I mean by retro food is dishes that saw their heyday in the 40s, 50s, 60s or 70s, but are now either largely forgotten or considered infra dignitum.
I'll start off by nominating fondue. Now fondue is not completely off the radar these days, but I'd wager it is nowhere near as popular as it was in the late 60s and early 70s. Absolutely love that bubbling raclette with the white wine and kirch.
