Chicago's top 5 private city clubs continue to innovate and remain ever-relevant in the Chicago social scene. They're paying attention to the latest trends of courting younger members and making it easy for members to stay plugged into technology when visiting the club. The Union League, for example, has carved out a unique niche by constantly varying club activities, maintaining the highest level of excellence in customer service and even making major contributions to the Chicago community through charitable organizations like the Boys & Girls Club. "This is a group of people who work hard and are serious, but they come here because they like to socialize and enjoy themselves," said Union League Board Member Rebecca Thomson. "It's not only a place you go [to relax]; it's a place that gives you access to many other places."
