If you ever find yourself in Chicago and want to avoid the tourist trail, I'd love to give you recommendations. Here are a couple nearly free options to get you started:
"Logan Hardware is a record store and vintage arcade museum located in the Logan Square Neighborhood.
A collection of historic games that are FREE to play!
Your patronage of the store helps us keep the Museum free and functioning."
"In addition to being the coolest store on the planet, we are also a curiosity cabinet of items resurrected from the past. A motionless zoo & touchable museum, we specialize in antique & vintage: specimens, taxidermy, art, medical doodads, atypical collectibles, unusual objects, & strange whatchamacallits."
