What are some of the best wine shops in downtown Chicago?
I completely agree with the Red & White and Perman recommendations! Perman in particular has some amazing low production stuff while still managing to have a nice range price point wise. Vin Chicago is also a go to spot. It's in a bit of an odd location - smaller than a Binny's but not boutique by any means. The staff is super friendly and knowledgeable and they will send you tech sheets/info on the wines you buy if you're interested.
