It is a very unknown attempt at a fast food chain from the 70’s that had John Browns backing (the guy who expanded KFC). I know this won’t get much traction due to lack of name recognition but it had 100+ locations at one point and has a really interesting story. Here’s a link to an article detailing the story and current state of the chain (yes it still sorta exists) if you’re interested https://bittersoutherner.com/ollies-trolley-worlds-greatest-hamburger
