Cost: $40 in advance, $45 at the gate ($70 for a two-night pass)

Organizer: Old St. Pat's Church

What to expect: Thousands of people, music, food and raffles.

Why to go: Oprah called it the place to meet your match after more than 70 couples met here and later married. If you value your book club membership, you'll go. Also, Barenaked Ladies headlines on Friday (Kris Allen and Angel Taylor will also play).

Additional info: Old St. Pat's Church is Chicago's oldest public building, and the event raises funds for its ongoing campus expansion. The Block Party typically sells out early, so get your tickets in advance. Five drinks are included with admission. The main gate is at Madison and Des Plaines.
