The very exclusive feel of the Park Hyatt's palatial indoor lounge and rooftop terrace bar has made Xiu a hotspot in Beijing's ultra-luxe nightlife scene. Located on the sixth floor of the hotel, the interior design mixes traditional Chinese architecture and contemporary lines to stunning effect. But it's the outdoor terrace, designed like a traditional courtyard, with stellar views of the city, that's the real draw. Bartenders mix creative but pricy cocktails like lychee martinis, while live bands rally the dance floor. If you're not in a dancing mood, there's plenty of space to sit and gawk. This is where the city's beautiful people gather to see and be seen. Looking your best is par for the course; the door policy is tough, so if you fancy joining the young, fashionable crowd, be dressed to impress.
