Crystals is a beautiful addition to the strip and City Center. Although not all of the stores have opened (Emilio Pucci and Gucci coming soon!) we enjoyed browsing through the ones that were open including: the largest Louis store I've seen outside of the flagship store in Paris, Tiffany's (a huge store with items I've never seen before), Dior, Porsche, etc.
There's lots of natural light that comes into the shopping center and it's not very crowded which is nice. I loved the decoration and materials used throughout the shopping center - it was a beautiful architectural structure not to mention a great place to shop!
There are also a few restaurants in the middle of the center including restaurants by Wolfgang Puck and Todd English. The top floor of the shopping center is not a complete loop, it's a horseshoe which is kind of confusing/annoying.
To top things off, Eva Longoria (Parker)'s club Eve is also housed here and the entire shopping center is environmentally sustainable, in fact, it's one of the world's largest environmentally sustainable urban communities! I can definitely support that!
