China's answer to Costco (until Costco arrived), German chain METRO doesn't have the nicest locations, but their distance from the downtown means that the warehouse spaces are absolutely massive. Vertigo-inducing shelves of pallets loom overhead while you're picking out 10-gallon drums of soy sauce. They also have the largest beer selection we've seen in China to date. This is where you shop when you need to do a dinner party for 20 teenagers and need chicken in party packs. Downside is that you have to sign up for a membership the first time you check out, but there’s no added cost, just a bit of irritation and some WeChat promotions.
