This legendary bakery on one of Paris’s prettiest pedestrian streets is the oldest pastry shop in the city—it opened in 1730 by the former pastry chef to King Louis XV. And if that isn’t a big enough accolade, he also invented rum baba. If that’s not your thing, this patisserie also makes a ton of other traditional baked goods like flan, eclairs, and financiers. If you’re in town during Christmas, their star-shaped spiced cookies make great souvenirs to bring back home.
