Overview: 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.
