Located at 15 Avenue Trudaine in Paris's 9th arrondissement, Léonie Bakery – Sacré‑Cœur embodies a modern, artisanal and organic approach. Taken over in 2019 by Kamel Saci, this branch adheres strictly to the brand’s ethos: organic or CRC-certified flours, natural leaven, at least 24-hour fermentation, bringing artisanal excellence to every loaf.

You’ll find signature breads such as the Léonie baguette, Tordu du Gers, Tourte de Meule, and more inventive loaves like Cœur de Sarrasin or Vollkornbrott. Viennoiseries are generous and expertly crafted – think butter croissants, cinnamon rolls, babka, kouign‑amann – regularly praised among the best in Paris.

The shop also features a cozy tasting area with indoor seating and a small terrace. A coffee corner, in partnership with L’Arbre à Café, serves top‑quality espresso, flat whites, matcha lattes and iced coffees via a premium Marzocco machine.

The interior blends contemporary style and warmth: dark wood counters, burgundy polished concrete floors, and artistic accents deliver an urban retreat ambiance. The clientele ranges from locals and quality-seeking food lovers to tourists drawn in by word-of-mouth recommendations.

Some reviews note very high-quality products but critique the service as somewhat impersonal or brisk at times, though such comments are outnumbered by praise for the bread and pastries. Many customers return regularly for their weekday bread or weekend breakfast treats.

Practical details: open daily – Monday to Saturday from 7:00 to 20:30, Sunday from 8:00 to 19:30. While seating is available, the space is more of a bakery than a full café‑restaurant. Wheelchair access and pet friendliness are not explicitly available.
