A new Chicago bar guide has been released for the first time since 2002: Historic Bars of Chicago, which reviews Chicago's Top 100 most historic neighborhood taverns, dives, nightclubs, blues bars, jazz clubs, and bierstubes. You can get Historic Bars of Chicago on Amazon but you can only get a signed copy at http://www.historicbarsofchicago.com or by joining the author, Sean Parnell, for a book signing at John Barleycorn Memorial Pub (658 W. Belden) on Thursday, May 20 from 7-9pm or at Kasey's Printer's Row (701 S. Dearborn) on Thursday, May 27 from 7-9pm. Come learn things you didn't know about the bars you love, and to discover new ones with intriguing histories. Buying the book also gets you $45 off your next Chicago Trolley rental, which is great for bachelor/bachelorette parties, birthdays and corporate events.
