Aux Castelblangeois is a distinguished artisan bakery and pastry shop located at 168 Rue Saint‑Honoré in Paris‘s 1st arrondissement, near the Louvre. Nestled in the bustling heart of historic Paris, it offers a perfect fusion of traditional craftsmanship and culinary innovation.

Founded by Norman-born artisans Olivier Pottier and Mathieu Fabril, the bakery pays homage to their heritage through its name and approach. The bright, tidy venue showcases an array of breads—from classic baguettes to seeded varieties and rustic round loaves—and exquisite pastries such as Saint‑Honoré, Mont‑Blanc and chocolate praline mousse creations.

Throughout the week, guests can choose from some thirty creative sandwiches—salty or sweet—ideal for a quick bite near the Louvre: think apple‑raisin‑country ham or curried chicken with peppers. The friendly, no‑frills atmosphere appeals to both locals and tourists seeking quality at fair prices, with a typical review rating around 4 out of 5.

A highlight: their Galette des Rois, crafted with buttery puff pastry and superfine almond frangipane, distributed from several locations including this one during Epiphany season.
