I Never Thought I'd Eat One of Those
Wangfujing snack is crazy place to get a meal. The alley is packed with people and vendors, and even if you're not eating, it's worth going, just for the experience.
There are tasty scorpions on a stick, or maybe you'd rather goat tripe soup and fried stinky tofu? Additionally there are great, perhaps more 'normal,' foods to be had here, such as yangrou chuan (pronounced yong row chuar), grilled mutton on a stick, fried noodles, and all sorts of candied fruits.
Certain side streets off the main drag house restaurants, and others are home souvenir markets that are a great place to practice haggling over prices (China's national sport). Wangfujing 'snack street' is not to be missed.
