What are some of the best wedding venues in Chicago?

In addition to the typical grand hotels, such as The Drake, The Four Seasons, and Chicago Hilton and Towers, there are special venues through the Chicago Park District (http://tinyurl.com/chiwedspecial). Weddings are held at Navy Pier's Crystal Gardens, The Chicago Cultural Center, and private clubs such as The Union League Club, The University Club, and The Standard Club. I've seen ceremonies held at Buckingham Fountain, The Lincoln Park Conservatory, and at the Gazebo on East Lake Shore Drive -- there are countless terrific wedding venues!
