Open steak sandwich and bowl of beer battered chips with aioli and ketchup.
The midwestern US is strange about Ketchup/Catsup. Some folks put it on eggs or steak or just about anything. But there are many (especially in Chicago) who will mock you for putting it on a hot dog. (It seems universally fine on a hamburger, but I can't even conceive of putting it on italian or polish sausage or a bratwurst).
