San Ping was working as a waiter in an unknown restaurant and accidentally swallowed a mysterious spice called "Taotie Tears". From then on, he not only saw monster diners disguised as humans, but also was burdened with the curse of "must collect 100 satisfied smiles to survive." He was forced to embark on a journey to solve the troubles of various monsters (such as the lovelorn nine-tailed fox, the anorexic Dragon King, and the homesick ghost) through cooking, and finally uncovered the mystery of his life experience and used food to resolve the war between the spiritual world and the human world.
