Carton Paris is a bakery near Gare du Nord in Paris that sells croissants, tarts, and cakes. The plain croissant is the signature item, with a deep butter flavor and a flaky texture, and there is also a version filled with raspberry jam. Even when the line is long, many customers get takeout, so the line moves quickly, and there are two checkout counters. The shop tends to be crowded because of the volume of people.
