Since mid-March 2025, the Experimental Group has transformed the former Sinner Hotel (116 rue du Temple, Paris 3rd) into the Experimental Marais, a 5-star boutique hotel with 43 rooms. Its food and beverage program now embraces a New York-style brasserie spirit, led by Chef Mélanie Serre.
Interior designer Tristan Auer, behind the hotel’s original look, returned for light updates. The bar kept its counter, refreshed with new furniture, and now offers a menu centered on American classics, drawing from the group’s experience in New York.
Signature Cocktails at the Bar

Maxence Gatebois-Lavalle, formerly of Hôtel des Grands Boulevards, leads a four-person bar team. Three signature creations headline the menu:

Fusion: A fruity, acidic blend with Quattro Gallos pisco, umeshu, peony, and rhubarb.
-
Mysterious Traveler: A bold, bitter short drink with blended vermouths, Pierre Ferrand cognac, and cocoa-infused sherry.
-
The Expedition: A sparkling long drink with Plymouth gin, pandan, passion fruit, and za’atar.
