Pâtisserie, boulangerie, and viennoiserie are French terms that describe different kind of pastry and the shops the said pastries are sold in. Let’s start with the first one.
Pâtisseire
Pâtisseire is a word that describes French pastries made by a licensed maître pâtissier — master pastry chef. In France and Belgium, only the bakeries that employ such chefs can be called pâtisseries by law.
Boulangerie
A boulangerie is a French bakery that sells breads like baguettes and pain de champagne.
Viennoserie
Viennoserie is the name for Vienna-style pastries that originate from Austria but are a big part of French cuisine. It includes pastries like croissants, brioche, pain au chocolat, and many more.
