Plot summary
Maggie's 16th birthday approaches and Fran intervenes in Maxwell's plans for her party. Instead of a boring party at the Guggenheim Museum, Fran convinces Maxwell to host it at her "Tanta" (Aunt) Frieda's club. Maggie loves the idea, but before the party can take place, Fran has to solve a serious family feud: her mother and Frieda ( Lainie Kazan ) have not spoken since 1979. The sisters-in-law eventually make peace with some prompting from Fran (and Niles's chocolate cake), and the party begins. During the event, Frieda has a wardrobe malfunction when she emerges from the bathroom, which reminds her of why she and Sylvia fought in the first place. They start a food fight which quickly spreads to the whole party. When Maxwell enters, he is shocked and about to scold Fran when Maggie thanks them for the best party ever.
