Barring the schlep to the touristy parade of Wangfujing, a visit here will usually prove worthwhile, and there's a good chance you'll find what you're looking for – probably at the best price in the city, too.
Passing the translations of Xi Jinping Thought that greet you on arrival, the ground floor is well stocked with English-language fiction new and old. (Using the omnipresent Penguin Classics imprint as a guide, we found them to be cheaper here than anywhere else, priced almost always at 68RMB.) The non-fiction range is also good, and an overflow section of older editions can be found up one floor.
There's a colourful Japanese magazine area up on level three, next to the requisite art and design section, as well as an overly extensive audiovisual department featuring CDs, DVDs and even Rosetta Stone cassettes, all of which largely collect dust these days.
