Department Stores and Malls

Beijing is the kingdom of malls and department stores. The best thing in Beijing's malls is that they're usually pretty empty, so you'll have all the space you could ever wish for in Western countries.

Malls at Oriental Plaza,  1 Dongchang'an Jie

Oriental Plaza is a huge complex. It's got the Grand Hyatt Hotel, plenty of offices and of course the big mall. At the mall you've got everything from an American-like-food store, food court, apple retailer, record shop with lots of extra-cheap records, Starbucks, Nautica, Levi's, Swarovski, Paul Smith, Valentino and many other luxury boutiques.

Sun Dong An Plaza, 138 Wanfujing Daije

Here you've got Western labels for everyone to share. Reebok, Nike, Däagen Haz, FCUK; it's all here. At the moment it's under construction, because they're making it even a bigger  shopping paradise for the Olympic tourists. 

Pearl Market (Hongqiao Market), 16 Hongqiao Lu

Don't be fooled by the name. While the Pearl Market does sell its name-sake, it also sells just about everything else. If you want to bone up on your bargaining skills, check this place out. Just remember, a lot of it is knockoff, so be wary if you plan on buying pearls (better to bring along a guide, if possible).
