Upon entering the high-ceilinged lobby, you are greeted by an eager polyglot staff and ushered onto an ottoman for check-in by tablet computer. Celebrity architect Kengo Kuma created the hotel's emerald glass exterior as well as the shimmering chain mail screen that swoops from the lobby ceiling. The 99 guest rooms are quieter in feel, evoking a Japanese minimalism with ingenious built-ins and natural brushed-oak floors. Floor-to-ceiling windows flood the rooms with light while blocking out street noise, even here in the Sanlitun nightlife district. Bei restaurant, which serves north Asian cuisine, draws a local crowd. Cocktails from the fabulously wicked Punk bar can even be sent to your room.
