Aldéhyde – the Marais table reborn under new hands

On a quiet stretch of rue du Pont-Louis-Philippe, a few steps from the Seine in the fourth arrondissement, Aldéhyde takes its name from a family of molecules that give certain plants, flowers and spices their most unmistakable scent – intriguing, divisive, memorable. It is a fitting signature for a kitchen built on surprise rather than consensus. The restaurant opened in September 2024, founded by chef Youssef Marzouk together with three friends from Paris's grandest kitchens, and it holds One MICHELIN Star, awarded in March 2025, barely six months after the doors first opened. Since September 2026 the house has changed hands from within: Marzouk's former deputies, Louis Beaurepaire and Julian Patary, now compose the menu together, while Thibault Blanche, the fourth founding friend, continues to run the dining room. It is a rare story of succession rather than reinvention, a small Marais address passed between people who built it side by side.

01The room and the setting

Aldéhyde occupies a small, luminous space on a side street running up from the Pont Louis-Philippe, close enough to the river to feel its quiet. The interior was designed by Séverine Nenciarini, who set an open kitchen against a dining room where rough stone and soothing green walls sit together, giving the room an organic, understated warmth rather than the formality of a conventional gastronomic address.

The open kitchen remains central to the experience: cooks step out to present dishes themselves, closing the distance between the pass and the table that defines so much of the restaurant's character.

02The chefs

Julian Patary trained first at the Carlton in Cannes, then learned wood-fired cooking in Strasbourg before joining Le Tout-Paris, the brasserie of the Cheval Blanc hotel, where the discipline of palace kitchens shaped his style. Louis Beaurepaire began at the bottom, washing dishes at Chamberlain's Restaurant in London, before working under chef Franck Martinez in a small team and later joining the Ritz for its reopening, an immersion in haute cuisine that set the course of his career.

Insider tip

Book ahead; lunch and dinner tasting menus only, four to seven courses.

Thibault Blanche, the dining room director, trained at Le Cinq at the George V before discovering sommellerie alongside Michael Lhéritier, building a style of service rooted as much in manner and elegance as in a refined knowledge of wine. The three met while working together in some of Paris's grand houses before deciding, with Youssef Marzouk, to open their own address in 2024.

Beaurepaire and Patary had already been composing dishes alongside Marzouk as his deputies from the opening. When Marzouk departed in September 2026, the pair stepped up to take joint charge of the kitchen, with Blanche remaining at the helm of the room.

03The cooking

Under Marzouk, the kitchen built its identity on a French repertoire inflected with his Tunisian origins, a sparing use of spice, herb and citrus. With Beaurepaire and Patary now writing the menu together, the cooking has shifted toward a more personal, purely French register, built instead around vinegar, fermentation and maceration, sharpened by pointed vegetal condiments that wake up classic technique.

Dishes are composed by the two chefs together, a back-and-forth search for balance between surprise and comfort, taking the French gastronomic canon and lifting it with a clean streak of acidity or a sharper, more vegetal edge than tradition would usually allow.

04What to order

The carte runs as a sequence of tasting menus rather than à la carte dishes. At lunch, a four-course menu (Prélude, La Mer, La Terre, Final) is priced at 75€, available only at midday. In the evening, the five-course Menu Éclosion (Amuse Bouche, Prélude, La Mer, La Terre, Final) runs at 110€, while the seven-course Menu Signature adds an Introduction and a Préambule Sucré ahead of the final course, priced at 135€ and served only at dinner.

05Wine and drinks

Each menu has its own pairing: 45€ for the lunch menu, 60€ for the Éclosion and 80€ for the Signature, put together by Thibault Blanche, whose service style draws directly on his training in sommellerie under Michael Lhéritier.

06When to go and booking

In October 2026, Aldéhyde serves lunch from Tuesday to Friday between noon and 1pm, and dinner from Tuesday to Friday between 7.30pm and 8.30pm. Given the restaurant's size and its single star, booking ahead is the sensible course, particularly now that a new kitchen team is settling into its own rhythm.

07The neighbourhood

The address sits in the heart of the Marais, a short walk from the Seine and within reach of the Pont Marie, Saint-Paul and Hôtel de Ville métro stations, a quiet residential pocket of the fourth arrondissement that keeps its distance from the district's busier boutique streets while remaining close to all of them.

For a weekend. For a lifetime.
