Un je ne sais Quoi...

Un je ne sais Quoi is a French pastry shop and café in Washington’s Dupont Circle area. Its pastry selection includes viennoiseries and classic French desserts, with the merveilleux—a meringue-and-cream confection associated with northern France and Belgium—among its best-known specialties. Coffee, French tea and juices accompany the pastries, and the shop also offers breakfast items. Its focus is French baking and pâtisserie rather than a full-service restaurant. The business’s linked ordering site did not expose readable menu details during this review.
