The elevated sidewalks in RiNo give wanderers the feeling that they're walking through a well-preserved Clint Eastwood set rather than a booming creative scene. On the first Friday of the month in the River North Art District, you can pop into numerous open-door galleries to see what  architects, designers, sculptors and woodworkers are creating. The Source, a 25,000-square-foot European market, is one of the city's top foodie destinations.
