Mmmmmmm.... le "Mont Blanc" de chez Angelina, rue de Rivoli ! - "the holiest of holies of a dessert, which they are famous for at Angelina's, the Mont Blanc. Chestnut puree filled with whipped cream! Some brave souls actually have this with Angelina's super-rich hot chocolate (which is just melted chocolate, I swear). Definitely not a size zero now"
