Does anybody actually shop at those places?
I was there last month. I had to walk past all those shops to get to Starbucks. I wouldn’t buy anything from them even if I could afford it. Really ugly stuff.
Celebrities. We've talked with staff at one of the major clothing stores at Crystals Mall at Aria. Many huge headline names come there and charge absurd amounts for designer apparel. And there are the usual collection of wives and girlfriends (sometimes shopping together) of Middle Easterners, Russian mafia, Chinese factory owners, and L.A. drug dealers who keep the Las Vegas economy afloat even in the worst of economic times. :)
Those stores aren't intended for Middle Americans like us with a modicum of sense. They are strictly going after impulse purchases by high rollers.
