The Project for Public Spaces, a nonprofit dedicated to creating and sustaining public places that build communities, recently named Chicago's Devon Avenue one of the best public spaces in the world. They note that Devon "has managed to retain its identity and strong social fabric rather than giving way to the pressures of gentrification." But before you get too proud about the city, know that Chicago is also represented on the nonprofit's list of the most overrated public places in the world by, of course, Millennium Park ("There is spectacle to behold, but not the variety of experience necessary for a truly great public space").
