"It feels wrong to call Crystals a mall, even though that's technically what it is, a short walk from the Waldorf Astoria. It's an art-filled retail district on the Las Vegas Strip with the world's largest luxury brands, from Tom Ford to Bulgari, Gucci to Harry Winston. It's often the first place where limited edition or exclusive release products will drop. Even the stores themselves are extremely special: At Stella McCartney, you'll find a life-sized, 8,000-Swarovski-crystal chandelier replica of her mother's horse, Lucky, which once hung in Belsay Castle. And at Tiffany & Co., you can go shopping and then pop the question on their proposal balcony. A Princess Diana tribute exhibition containing several of her evening gowns, gifts and correspondence now lives on the third floor. And among the very good dining here is a new José Andrés restaurant, Bazaar Mar, devoted to seafood." - Andrea Bennett
