Ain't the counties adjacent to Iowa much more hipsterous than Cook County?
That area, both rural and urban portions, is heavily working-class whites. You'll find far more hipsters in Bloomington-Normal than you'd find in Peoria or Rock Island.
Actually Peoria has quite the scene. Also the home of cult Christian hardcore band Subsist.
Peoria has a bit of everything, as it was known to throughout the 20th Century. Large Black population, lots of working class Whites, the Warehouse District has quite a yuppie character now a days, a very large and influential business community, etc.
