Sacha Finkelsztajn (La Boutique Jaune)

Sacha Finkelsztajn, universally known to regulars as La Boutique Jaune for its bright yellow storefront, has operated on Rue des Rosiers since 1946, making it one of the oldest continuously family-run businesses in the Marais's historic Jewish quarter. The shop was founded by the current owner Sacha's grandparents, Eastern European Jewish immigrants who brought Ashkenazi recipes and baking traditions with them, and the family has maintained those recipes largely unchanged across three generations. The pastrami sandwich is the shop's best-known item, cured and smoked meat piled generously into rye bread, and stands as one of the more distinctive sandwich experiences in a city otherwise dominated by classic French jambon-beurre. Beyond the sandwich counter, the shop functions as a full delicatessen and bakery: cheesecake, apple and poppyseed strudel, blintzes, chopped liver, herring preparations, and an assortment of savoury pastries including a well-regarded piroshki fill the display cases, reflecting the full breadth of Ashkenazi Jewish culinary tradition rather than a narrow tourist-facing selection. The shop is compact, with most business conducted at the counter for takeaway, though a handful of small tables allow for eating on-site. Its location on Rue des Rosiers places it directly among the strip's other Jewish-owned businesses, including several falafel counters, giving visitors an easy way to sample multiple facets of the neighbourhood's culinary heritage within a single short walk. Sacha Finkelsztajn closes on Mondays and Tuesdays, a schedule tied to the rhythms of a genuinely long-running family business rather than tourist demand, and remains, alongside its falafel-focused neighbours, one of the clearest living links to the Marais's identity as a historic centre of Parisian Jewish life.
