Grandmaster Games - Oak Park

They have a surprisingly decent selection of board games considering their small footprint, and their prices are acceptable. You can usually find a good deal on something 10-30% off on occasion too, if you aren't picky.

After having a board game night with some friends, I couldn't stop thinking about one of the games we played - this place had it! Their selection was wider than I thought it was going to be, the staff member there was very nice, and they had a ton of board games on sale as well. Price for the game I wanted was cheaper here than I saw it listed for online as well.
