The disastrous dinner party is a Housewives tradition. OG RHONY cast member Dorinda Medley hosted many a demented meal at her infamous Berkshires manse in the 2010s; the seminal "Real Housewives of Beverly Hills" episode "The Dinner Party from Hell" is perhaps the single best episode, beat for beat, that Bravo has ever produced.
The dinner party at the center of the fourth episode of RHONY season 16 is much less iconic than its forebears, but at least it's something.
