If you enjoy music under the stars, the outdoor concerts at Ravinia are a stellar treat. Ravinia Festival, a summer-long series of performances, is the hot-months' home of the Chicago Symphony Orchestra, but the festival also features popular jazz, chamber music, rock, pop, and dance acts. Pack a picnic, bring a blanket or chairs, and sit on the lawn, often for little more than the cost of a movie. Large screens are placed on the lawn at some concerts so you won't miss anything. Seats are also available in the pavilion for a significantly higher price. There are restaurants and snack bars on the park grounds, so if you forget your goodies you still won't go hungry. Concerts usually start at 7 or 8 pm; the park usually opens two to three hours ahead to let everyone score spots and get settled. Weekend-morning concerts are aimed at kids. They feature a "KidsLawn" with an interactive music experience, and on select dates an "instrument petting zoo," arts and crafts, and live performances. During the off-season, check out the Fall and Spring Series of indoor concerts at Bennett Gordon Hall.
