From way off Broadway to slightly off-Broadway comes the Chicago-born phenomenon Flanagan?s Wake. One of the longest-running shows in Chicago theater history makes the jump to NYC by way of the intimate Sweet Caroline?s theatre. For $20, you'll get one ticket to the show, a $50 value. Your Groupon can be used at any performance you want, but not for stealing hats backstage. Choose between: Mondays, Thursdays, Fridays, and Saturdays at 7:30 p.m.; or the Sunday matinee at 4:30 p.m. The runtime is approximately 90 minutes with no intermission, so regulate your liquid intake accordingly.Follow @Groupon_Says on Twitter.
