I suppose it is fitting, and not at all a coincidence, that the largest mall in the world (Dubai Mall) sits adjacent to the tallest man made structure in the world (Burj Khalifa). If my calculations are correct I think it feasible to maneuver a Boeing 747 through the corridors of the mall. You name it, it is there. They even have a huge ice skating rink (not to be outdone by the Mall of the Emirates which has an indoor ski slope). Why not? The Dubai Mall also has the best aquarium and underwater zoo I have even seen in a mall or otherwise. I must admit it was pretty darn neato (First two pics below from the internet).
And then there is the Ibn Batuta Mall which has international themes. I had the pleasure of window shopping in China, India, Egypt, Tunisia, Persia, and Andalusia. Don't want to walk? Well, hop on the golf cart taxi for your international shopping tour. Of course, if you do and you are not suffering from some sort of physical malady then you are more than a little pathetic.
