Chicago's finest 'pork project' in decades, it features surprising architecture and art that are all interactive in some way. In nice weather, you'll find dozens or hundreds of kids playing at Crown Fountain, with two towering digital screens showing the smiling faces of Chicagoans in slow-motion.
The city also offers free performances in the Gehry-designed Pritzker Pavillion. There's a bike centre to rent or stow a bike, a large garden, skating rink, restaurant and spectacular views of both the lake, and the most elegant stretch of Michigan Avenue.
My favorite part? The world's only Gehry bridge, which meanders like a lazy stream, and leaps across Columbus Avenue, tranporting you into another large park.
On Michigan Avenue between Randolph and Monroe.
One block from the Loop, served by every elevated train in the city, numerous buses, and several underground garages; www.millenniumpark.org/
