On a Sunday evening in Taipei, semi-retired chef and widower Zhu prepares a feast for his three daughters. Jia-Jen, the eldest, is a chemistry teacher who devotes herself to Christianity after facing heartbreak from her college ex-boyfriend. The second daughter, Jia-Chien, is an executive at an airline company. She wanted to become a head chef like her father but he claimed that it was not for a woman. Jia-Ning, the youngest, is a college student who works part-time at a Wendy's fast food restaurant.
At dinner, Jia-Chien announces that she has invested in a new apartment and will be moving out once construction is complete. Surprisingly, Mr. Zhu approves. Jia-Chien criticizes the flavor, claiming Mr. Zhu's taste is deteriorating. Mr. Zhu dismisses the idea before suddenly rushing off to help his (and Jia-Chien's) long-time friend and "taster", Old Wen, at a banquet. Afterwards, Mr. Zhu wonders with Old Wen if there is anything more to life than eating, drinking, man, and woman. Meanwhile, family friend Jin-Rong stops by the Zhu residence with her daughter Shan-Shan. Jin-Rong vocalizes her difficulties with a messy divorce while being responsible for work, Shan-Shan, and her opinionated mother, Madame Liang, as she returns to Taipei from America. Jia-Jen comforts her while Shan-Shan colors a caricature of Mr. Zhu.
The next morning, Mr. Zhu meets Shan-Shan, learns that the lunches Jin-Rong provides her are suboptimal, and decides to cook for her. Shan-Shan agrees, letting Mr. Zhu eat the lunches her mom made to prevent her from discovering their secret. At school, Jia-Jen meets the new volleyball coach Ming-Dao and they take interest in one another. Jia-Chien meets the chief negotiator Li Kai during a meeting at work and they flirt with one another. She has a chance to relocate to Amsterdam due to a potential promotion. Jia-Ning meets up with Guo-Lun, her friend Rachel's on-and-off boyfriend. As Guo-Lun mopes about his unrequited love, Jia-Ning comforts him, telling him that true love is being with someone he can express his feelings to comfortably, leading Guo-Lun to realize his love for Jia-Ning.
Meanwhile, Old Wen becomes hospitalized. Jia-Jen is fooled by love letters she believes are from Ming-Dao, falling for a prank by her students. Jia-Chien's apartment investment falls through as she discovers that the apartment company went bankrupt and ran away with her savings. She also learns that it was Li Kai who broke Jia-Jen's heart in college and confronts him about it. Li Kai says he never dated Jia-Jen. Jia-Ning faces a dilemma when she begins dating Guo-Lun even after Rachel confesses that she loves him. Mr. Zhu's health deteriorates and secretly visits the hospital, unaware that Jia-Chien saw him while visiting Old Wen. Eventually, Old Wen passes away and Mr. Zhu concludes that his sense of taste has officially departed.
At another Sunday feast, Jia-Chien announces that she will no longer be moving out; Mr. Zhu tells her not to worry. Later, Jia-Ning reveals her relationship with Guo-Lun and her pregnancy. The next dinner, Jia-Jen divulges that she and Ming-Dao have eloped. Jia-Jen and Jia-Ning move out of the residence, leaving Mr. Zhu with Jia-Chien. Troubled, Mr. Zhu begins to confide in and meet Madame Liang, leading the daughters to believe that the two are romantically involved.
Worried about her father's health, Jia-Chien rejects her promotion. Soon, the sisters, their partners, and Jin-Rong's family gather for a large Sunday feast. Mr. Zhu announces his engagement, not to Madame Liang, but to Jin-Rong, also revealing that his visit to the hospital was to show good health to gain Madame Liang's blessing. Madame Liang goes into shock, abruptly ending the dinner. Later, Jia-Ning and Guo-Lun have their baby, Jia-Jen converts Ming-Dao to Christianity, and Mr. Zhu sells the family home and buys a condo with Jin-Rong and Shan-Shan. Jia-Chien, no longer needing to take care of her father, accepts the job in Amsterdam. Before she leaves she prepares a final feast for the family in the family home, but only Mr. Zhu arrives. When Mr. Zhu tastes her cooking he suddenly realizes that his sense of taste has returned. The two hold each other’s hands in the dining room, and call each other “Father” and “Daughter”.
