A "boulangerie" is the French word for French bakeries. They are the businesses selling bread, pastries, and "viennoiserie." The French Law makes a difference between a French bakery (Boulangerie) and a pastry shop. According to the law, bakeries must make bread on-premises to carry the title of "boulangerie." Boulangeries can sell pastries, but their primary trade must remain traditional French bread.
