After reading reviews on various websites and looking for a jazz club in Chicago, we decided to visit Underground Wonder Bar. On one website I found a password so you did not have to pay cover. Thank goodness for that. We went into the bar and sat at very uncomfortable, unstable table. The band played very eclectic jazz...not what we were expecting. We did stay for one band's set, but then decided to leave. The drinks were a little pricey for such a dive joint. I wish we would have just went to Andy's.
