Now, in a move that will delight nostalgic fast food fans, the multinational chain, which still has around 80 outlets in the UK, has revealed plans for a major expansion.
The brand, which once had over 500 eateries around the country during its heyday in the 60s and 70s, plans to battle back after struggling in the face of competition from fast food giants like McDonalds and Burger King.

A Wimpy spokeswoman told the Daily Star that they have "exciting new plans in terms of continued expansion and an investment programme" which wouldn't be detailed properly until May next year.
However, before Wimpy fans get too excited, retail experts have warned that it might not be an easy task for the struggling brand to get back on top.
Food and drink consultant Peter Martin told the Daily Star Online: "If they were to do it, I'd be surprised. I think it's a very difficult market for them to come back into. It's always very difficult bringing back old brands – nostalgia only works with old people!"
Martin added that Wimpy would have to do something "special" as bigger brands like McDonalds, Greggs and Wetherspoons have already stolen a march on them in terms of efficiency, healthy alternatives and quality.
Originally a Chicago based company which launched in 1934, Wimpy made the transition to the UK in 1954 where it became many British household's first exposure to American style fast food.
The burger company is now owned by the South African based Famous Brands, who also snapped up British burger chain Gourmet Burger Kitchen (GBK) in 2016.
