Union Bakery was founded in early 2021 by Charles (bread enthusiast) and Maéva (pastry specialist), after stints at Yann Couvreur and Plaza Athénée. They opened this airy location at the corner of Rue Bleue, in Paris’s Faubourg‑Montmartre district, aiming to offer high‑quality bakery and pastry accessible to the neighborhood.

Every morning, a mirrored counter and visible open kitchen showcase French and organic flour‑based creations, including their signature “market bread” made from ancient low‑glycemic grains, which quickly became a favorite.

Signature items include golden buttery croissants, generous pain au chocolat, cinnamon buns, fluffy babka, and a chunky chocolate‑hazelnut cookie (around €3.20). Also on offer: balanced vanilla flan, surprising raspberry‑pepper tart, pistachio‑chocolate escargot, pesto‑tomato‑arugula veggie sandwich, and fresh gourmet salads.

The style combines industrial chic with warmth—exposed brick, large display windows and minimalist decor. The atmosphere is cozy and informal, perfect for takeaway or a quick stand‑up snack.

The clientele is varied: parents, young professionals, locals and food lovers are all welcome. Union emphasizes community and quality without pretension. They also collaborate with nearby artisans—such as a local coffee roaster for their “Fat chu Kafé” pastry—and supply pastries and breads to neighboring Hey Honey restaurant.

Opening hours are Monday to Friday from 8 AM to 8 PM, Saturday from 8 AM to 3 PM, closed on Sundays. To avoid queues, it’s wise to go early or around midday, especially since offerings often sell out by afternoon.

Union Bakery consistently receives acclaim in local guides for its cookies and babkas. With hundreds of reviewers rating it around 4.8/5, it’s considered a top spot for quality and value in Paris.
