The Westin in Xi'an is a giant fortress of a building, It's quite a fun place to stop. It's full of gorgeous Chinese antiques.
The Lobby Lounge is beautiful, you enter it down a long hallway guarded by dozens of large candles. They have a great deal on Moet & Chandon champagne and a piano player on the weekends. The service is the highlight–professional ladies who make everyone feel welcome, no matter who they are.
There's an amazing gallery and high-end shop just off the lobby of the Westin hotel. It has stunning examples of classic Chinese jewelry, and art such as jade Buddhas and hand-carved horse statues. Outside of the store is a beautiful atrium where you can sit and have a coffee or read a book.
