"From June to September, The Jay Pritzker Pavilion in the Loop is one of the best places to listen to live music outside. Here, you can listen to a set from Wilco frontman Jeff Tweedy, return for some Tchaikovsky with The Grant Park Orchestra, and then come back on a weekend for Jazz Fest. Outside food and drink is allowed, which makes these concerts perfect for picnics. But if the mere thought of formulating a plan dries out your tongue, you can just grab a beer and bratwurst from one of the surrounding concession stands.
