There’s a touch of the traditional Chinese teahouse to this excellent restaurant, housed in a reconstructed two-storey interior courtyard, and bubbling with old-Peking atmosphere. The menu is based on a Qing dynasty imperial recipe book known as the Golden Soup Bible, and the dishes are consistently good (and fairly priced considering the quality).
The imperial Manchu theme could be tacky, but it’s carried off in a fun but tasteful way. You don’t need to book (in fact, at peak times you can’t), but be prepared to hang around for at least half an hour for a table. It’s worth the wait. No English sign and not much English spoken, but the menu is in English.
