“In addition to Cupcakes & Co., there is Berko, an American-style French bakery with outposts in the tourist-friendly Marais and Montmartre quartiers, serving circus-like flavors such as banana and Nutella, tarte tatin, and Oreo. Across town in Saint-Germain, Synie's Cupcakes takes the elegant route with chocolate ganache, lemon ginger, and dulce de leche with sea salt.”
