Who spends a Saturday night at IKEA? A lot of people it seems, including this photo's photographer! In 2009, IKEA at Furuset in Oslo was estimated to have about 90 000 visitors per week. There is no need to think the amount of people going there are any less 4 years later. In 2012, all IKEA's warehouses had 690 millions visitors. That is a lot of Billy book shelves sold!
