Storyville

First in a four-part series looking at China's largest restaurant looks at what it takes to run a successful restaurant business in China.

Part 3 looks at the strong sense of duty implicit in family relationships in China. Waitress Peng has sacrificed her own education to support her sister's studies, while owner Qin Linzi discusses her own difficult childhood and introduces us to her privileged daughter. The restaurant prepares a 70th birthday banquet for Sun and her family, with special dishes including steamed longevity buns and stir-fried turtle.

Part 4 looks to the future with a banquet for a new baby and the anniversary show organised by the West Lake to celebrate its third year. Managers, chefs and waiting staff take to the stage in an all-singing, all-dancing extravaganza rounded off with a star turn by the owner, Qin Linzi. The restaurant addresses the high rate of staff turnover and gives the waiting staff a pay rise, while Qin discusses how important it is for her to drink with her customers.
