I guess this fits under the category of a screen used prop.
Coming To America is one of my favorite movies ever. So I took a 20 mile detour from where I was running errands to stop and take a picture of where the famous "McDowells" was on film.. The building is still the same, only the roof if different. To my knowledge it was always a Wendys as well. I'm almost tempted to throw together a uniform and go back with a mop.
