The play is set in the dining room of a typical well-to-do household, the place where the family assembled daily for breakfast and dinner and for any and all special occasions. The action is comprised of a mosaic of interrelated scenes—some funny, some touching, some rueful—which, taken together, create an in-depth portrait of a vanishing species: the upper-middle-class WASP. The actors change roles, personalities and ages as they portray a wide variety of characters.   Dovetailing swiftly and smoothly, the varied scenes coalesce, ultimately, into a theatrical experience of exceptional range, compassionate humor and abundant humanity.
