Man, where did I first eat at a Mr Quick...?.... North Dakota 30 years ago? Maybe Iowa?
There's the clearly recognizably shell of a Mister Quick just south of Oconomowoc WI. It was still in operation last decade but now I think it's a hairdresser.
(And what the heck is it about burger places turning into hair salons? I find more former Dog-n-Suds are now beauty parlors!)
