Right now I'm sitting in one of the restaurants overlooking Ski Dubai. There are people sliding down the hill on long, flat appendages attached to their feet. There are actually quite a few good skiers out there, considering it's in the desert.
Ski Dubai is just part of the massive shopping mall that is Mall of the Emirates. It's about four times the size of Bellevue Square by the looks of things.
Getting here via public transportation is interesting. A bus drops you on the opposite side of a 6-lane freeway, which doesn't have an overpass for miles. So, apparently you have to either jaywalk or take a taxi to the other side. I don't really recommend jaywalking across 6 lanes of Dubai traffic, but it can be done.
I've never seen a city that's less friendly to pedestrians than Dubai.
