Düsseldorf's main shopping avenue epitomizes the city's affluence, lined as it is with designer boutiques and stores. Known as the Kö, this wide, double boulevard is divided by an ornamental waterway fed by the River Düssel. Rows of chestnut trees line the Kö, shading a string of sidewalk cafés. Beyond the Triton Fountain, at the street's north end, begins a series of parks and gardens. In these patches of green you can sense a joie de vivre that might be surprising
in a city devoted to big business.
