Sanlitun was once a run-down district for young expats and broke students looking for a fun night out. But when the Opposite House, with its modern, green-paneled facade, landed in the middle of this formerly hedonistic paradise, things went distinctly upscale. Sure, there still are a few places just behind the hotel to get a quick drink, but now the area attracts a smart set of young Chinese urban professionals and local fashionistas. Designed by Japanese architect Kengo Kuma, the quirky exterior doesn't do justice to the Asian minimalist styling inside. The entrance itself is a work of art—the huge wooden door has the texture and rawness of age, with beautiful iron handles reminiscent of those adorning the gates in the hutong districts. Inside, find expansive wood floors, glass panels, and rotating art exhibits featuring local artists. The hotel’s restaurant, Jing Yaa Tang, offers one of the best dim sum deals in town, an all-you-can-eat brunch for $25.
