Are bigger shopping malls best?

Europe's biggest urban shopping mall has opened in the east end of London.

Westfield Stratford City has some 300 shops with nearly two million square feet of retail space.

It is near the site of the London 2012 Olympics and is promising to bring thousands more jobs to the area.
