It may come as a surprise to some that Nicolas Flamel, the philosopher of Harry Potter fame, actually existed in real life. Built in 1407, the house once belonged to this celebrated alchemist and local benefactor, and was converted into a restaurant two centuries ago. It has retained its original facade and now boasts the most charming of proprietors, Natan Hercberg, formerly of Paris's most fashionable nightclub, Les Bains. The food at the 'oldest house in Paris' fits the context: classic olde France. Don't miss the gigot de sept heures or the delicious tatin de Foie Gras aux pommes caramel. Ask Natan to show you the magical Salon des Anges before you decide whether to dine upstairs or down.
