Characteristic for the Ruhr are lots of kiosks in the suburbs, smallest shops for nearly erverything. Opened mainly from afternoon till late night they act also as a communication spot for the neighborhood.
The city centers of Duisburg, Essen, Bochum und Dortmund offer excellent shopping conditions.
Popular shopping centers are Centro (http://www.centro.de/engl...) at Oberhausen, Rhein-Ruhr-Zentrum (http://www.rheinruhrzentr...) at Mülheim, Limbecker Platz (http://www.limbeckerplatz.de/) in Essen and Ruhr Park Bochum (http://www.ruhr-park.de/). But the centers of the major cities offer also best shopping conditions.
