Three floyds is just one the other side of the state line, so you should be able to find it easily and dreadnaught is in season right now, but as for brew pubs goose island is good(even though they were just bought out, the beers that they are serving were still probably brewed before that haha)
Or you can go to the Binny's South Loop location (a short cab ride or nice walk) It is a beer store but after 3:00pm they have a nice selection of taps in there little tap room and they can also chill any bottle in the store for you. 3Floyds Arctic Panzer Wolf was still on the shelves last night, as were many other good beers.
