Even so, it's an interesting look at the foods we consider icons of decades gone by.
I think if I were to point to a food that I associate with, for example, the 80's... I would say (just for myself) Fruit Roll Ups, Prime Rib, and Pudding (the kind you cook in a pot). Oh, Pudding Pops and the Ecto-Cooler also.

Fondue is probably the ONE food you can definitely point to having it's heyday in a past decade.
