Chicago has an incredible food scene across the entire cuisine spectrum and only 1 thing on the list is "Chicago Style" (the hot dog)

while I wouldnt consider it on the same tier as like nola/creole/cajun cuisine for example, but its distinctive enough to get a name.

Food IN Chicago is good. The use of "Chicago style" outside of Chicago is largely a label for "this shit sucks."

Chicago Style "deep dish" is an affront to both to god and the deliciousness that is Detroit Style deep dish
