Serendipity 3, the kitschy upscale soda fountain–restaurant frequented by celebrities, debutantes, and tourists, announced today the creation of the world's most expensive dessert, the $25,000 Frrrozen Haute Chocolate. It's crowned by the world's most expensive piece of chocolate, the $250 La Madeline au Truffe, made with a whole Perigord black truffle and truffle oil. For $25,000, shouldn't Serendipity throw in some shaved white truffle as well? And shouldn't they donate half the proceeds to some worthwhile food charity?
