Hyper-expensive shopping venues are the Cornerstone of City Center. You'll see a lot of people window shopping, but not much buying going on. I've visited there on a weekend, and couldn't believe how dead it was in there. To be honest, even with the sticker shock, one wonders how they pay the rent for this place.
That being said, the free tram service between venues is the best feature this landmark has to offer. Don't get me wrong, the surrounding casinos as gorgeous, but the shopping mall they built in the center of this feels more like a soulless Rodeo Drive they plucked up and put in the middle of the dessert, only with a lot less foot traffic.
