Situated on rue Saint-Dominique in the aristocratic 7th arrondissement, Brasserie Thoumieux represents hotelier Thierry Costes' take on the traditional Parisian brasserie, updated for contemporary sensibilities. The interior, designed by India Mahdavi, balances heritage elements with bold contemporary touches that revitalize rather than reinvent the brasserie concept. The restaurant sits at the base of Hotel Thoumieux, creating a complete hospitality experience that attracts both hotel guests and Parisians who appreciate the kitchen’s commitment to brasserie classics executed with precision. The clientele reflects the neighborhood's upscale character—politicians from the nearby government ministries, elegant locals, and sophisticated visitors who have discovered this slightly under-the-radar gem. What distinguishes Thoumieux within the Costes universe is its deeper respect for culinary tradition while maintaining the group's signature aesthetic appeal.

Overlooking the iconic Place de la Bastille, Café Français represents the Costes brothers' contemporary reinterpretation of the classic Parisian brasserie. Designed by India Mahdavi, the space balances nostalgic brasserie elements with bold modern touches that create a visually striking setting. The expansive terrace offers front-row seats to the bustling Bastille intersection, while the plush interior provides a more intimate experience. What makes Café Français distinctive within the Costes portfolio is its neighborhood positioning—while maintaining the group's signature style and service standards, it feels more integrated into everyday Parisian life. You'll find a diverse clientele here, from opera-goers from the nearby Opéra Bastille to fashion industry professionals and residents of the trendy 11th arrondissement who appreciate the reliable quality and buzzing atmosphere.

Perfectly positioned beneath the arcades of the Louvre Museum with front-row views of the glass pyramid, Café Marly offers one of the most prestigious dining locations in Paris. This Costes group establishment balances its tourist-attracting location with an authentically chic Parisian atmosphere that keeps locals coming back. The interiors pay homage to French classical design with a contemporary twist, featuring rich red upholstery and marble tabletops that complement the historic architecture. While tourists snap photos of the Louvre from the terrace, fashion industry insiders and art dealers conduct business meetings inside. The service maintains the signature Costes blend of efficient professionalism with a dash of studied aloofness that has become part of the experience.

Nestled on the Place Saint-Germain-des-Prés, La Société is the Costes brothers' tribute to the Left Bank's storied intellectual history, reimagined through their contemporary lens. Christian Liaigre's interior design creates a sophisticated atmosphere with warm woods and leather banquettes that feels both timeless and decidedly modern. The location puts you at the heart of Saint-Germain's literary heritage, steps from Café de Flore and Les Deux Magots, yet La Société carves out its own distinct identity with a more polished, international approach. The clientele reflects this blend of tradition and cosmopolitanism—publishing executives lunch alongside fashion designers, while visiting celebrities appreciate the discreet service and relative privacy afforded by the intimate space. The terrace, while not the restaurant's main draw, offers prime positioning for observing the rhythm of one of Paris's most charming neighborhoods.

Tucked away in the increasingly fashionable South Pigalle district, Restaurant Amour brings the Costes sensibility to a more bohemian setting. Created by Thierry Costes in collaboration with artist and nightlife entrepreneur André Saraiva, the restaurant extends the concept of the adjoining Hotel Amour with a similar artistic, slightly risqué aesthetic. The garden terrace is an unexpected oasis in this densely urban neighborhood, offering a lush retreat that feels worlds away from the city despite being steps from bustling rue des Martyrs. The crowd skews creative—musicians, artists, and fashion industry figures who appreciate the relaxed yet curated atmosphere. While maintaining high standards of service and cuisine, Restaurant Amour feels less formal than other Costes establishments, with a playfulness that suits its name and neighborhood.
