The old son-must-eat-the-father rubric gets a fresh edge when the tyrannical father and his traumatized son are failures in the restaurant business. On his former restaurant's big night (a night of critics and Michelin inspectors), the chef- father found his wife cheating and stabbed her to death. At least that's what Julius has been telling his son in the lonely years since, while forcing the boy to wear a wig and pretend to be his own murdered mother. Fabulous Prizes, by Seattle playwright Neil Ferron, is a rewardingly demented new play that begins as a gallows comedy and ends with a shocking act of liberation.
