Hot Tix, the League of Chicago Theatres' discount ticket office, is opening its new Loop location today at 72 E. Randolph. Stop by between now and 5pm for free Starbucks coffee, ticket giveaways, and performances by the casts of shows like Wicked and Whose West Wing is it Anyway. Hot Tix offers half-price day-of and week-of tickets to shows at 125 Chicago-area theatres; the list of available shows is posted every day at HotTix.org, but must be purchased in person at the Hot Tix booths in the Loop, the Water Works Visitors Center, the North Shore Center for the Performing Arts in Skokie, or any Tower Records location.
