Titsou is the hidden 8-seat cocktail lounge tucked behind an unmarked sliding door in the lobby of Hotel Barriere Fouquet's New York — modeled on Bar Marta at Fouquet's Paris and named for Lucien Barriere ("Titsou" was his daughter's nickname for him). The room evokes 1920s-30s Parisian glamour: aubergine and amethyst palette, dark-green velvet, Art Deco lamps, tented-fabric ceiling, eight bar seats. Signature cocktails skew classic-reimagined — N.Y.G. Vesper, Fouquet's Fashion, Transatlantique, smoked Old Fashioned with a tableside cognac perfume-bottle spritz — paired with small bites (substantial French food lives at the hotel's separate Brasserie Fouquet's, not here). Wallpaper named Titsou to its 15 Best Bars in New York list. For a Parisian Art Deco speakeasy inside a French-luxury hotel — the entrance mechanic is real, the cocktails are credentialed by design more than awards.
