It's midnight. But walking through Guijie Street, a popular night destination in downtown Beijing, you would think it's a carnival evening. Lines of people pop in and out of the row of restaurants, and the mouth-watering smell of spicy crawfish wafting out stops passersby in their tracks and makes them head toward the source of the smell. At Huda Restaurant, a crawfish joint, people are still waiting in queue and connoisseurs say the dish there is worth sev-eral hours of waiting.
