In 2003 an artist collective from Guizhou-a poor province in south central China-arrived in Beijing to sell their paintings. To pay the bills and to keep from getting homesick, they opened this 24-hour restaurant named after themselves. Their art careers never took off, but their restaurant now has five branches. And they are always packed. The sleek gray dining room serves nouvelle Guizhou specialties like sour fish soup, lavender tea with milk, and mango and ice purée.
