There are so many different regional variants of hot dogs though. A Chicago dog isn’t a Nathan’s dog, which isn’t a Cincinnati coney,* which isn’t a Texas-style chili dog,** or the hot dogs with baked beans they have in parts of New England.
*Not to be confused with a Michigan-style coney
**From Pennsylvania, not Texas
Chicago style and New York style are completely different. They can barely be considered the same food IMO. If you go Downstate you get into St Louis pizza territory, which is different than either.
When I think Illinois food, I think Italian Beef sandwiches.
But if it’s bland food you want, you can have the Illinois Horseshoe or loose meat burgers. We’ve got plenty of that, if you go Downstate a couple hundred miles first.
