The Green Mill owner Dave Jemilo actively lets the audience know of the "listening rules" when introducing the act, whether or not the night's performance is being recorded. That respect for live performances is one of the reasons the club is so perfect for any jazz devotee. If you've never been there to enjoy the atmosphere and authentic Art Deco decor, please make the club a special destination for your next Chicago visit (you might want to wait a few days until our current arctic temps warm up a bit).
