From an article by Linda Marx in the July 21 New Yorker (the one with the infamous cover):
Is there anything you can't get in Shanghai? Here are some things that expatriates told me they crave: antiperspirant; One-A-Day vitamins; non-soupy yogurt; dark chocolate; opaque tights in interesting colors; bras that aren't gaudy, push-up, or padded; Tampax; stylish shoes with a decent high heel; porn magazines; real rye bread; Mexican food; cereal that costs less than $10; clothing and shoes in large sizes; avocados; Clairol Born Blonde All-Over hair color. It's also impossible to find souvenir snow globes, but this doesn't seem to matter to anyone but my nephew in Philadelphia.
So get with it, Shanghaiers!
