Kids just aren't ready for grown-up theater. The murderous garter-belt-and-stockings-clad floozies of Chicago are something that little ones can't (and shouldn't) comprehend. The Discovery Theatre Series, on the other hand, plies its junior audience with big, colorful productions seven times a year (from October through May) that stimulate the eyes and ears as well as the brain. Super-slick shows - often produced by national touring companies - are staged at Playhouse Square's spacious Allen Theatre. And the family-friendly ticket prices (usually less than $15) mean you can afford to catch more than one of them. Whether charming tots with Frog and His Friends, giving older kids a cultural lesson about the Children of Uganda, or talking straight-up to teens about Vietnam in The Things They Carried, the shows educate, enlighten, and best of all, entertain.
