Oh, don't mind the street running through the middle of the mall. It's supposed to be there. The Alto Palermo shopping center in Argentina is an architectural gem, with its mirror-like exterior reflecting the blue sky and surrounding buildings. Stores like Calvin Klein, Christian Lacroix, and Christian Dior will drain your pockets, but that's what you went shopping for, right?
