About Barts
Behind that black door on Sloane Avenue lies our peculiar world—a 1920s speakeasy where we've been keeping Chelsea's secrets since we first opened. You'll need the password to get past our doorman, and once you're through, you've stepped straight into 1929 Chicago. We've filled every corner with curious finds: taxidermy peers down from chintz-covered walls, antique mirrors reflect the amber glow of table lamps, and our leather banquettes have heard countless whispered conversations. The fancy dress box sits ready for anyone feeling adventurous—we keep it stocked with wigs, hats, and costumes that transform bankers into bootleggers and lawyers into flappers. Our bartenders pour cocktails into teapots and serve drinks in paper bags, sometimes setting them aflame, other times watching them change color before your eyes. These aren't just drinks; they're performances in miniature. Through a hidden door, you'll discover our Secret Garden—a tropical hideaway where palms and heating lamps create summer even in December. The retractable covering means rain never stops the party. We host up to 80 guests for private parties and corporate events, though most nights you'll find us packed with those seeking something different from their Thursday, Friday, or Saturday night. Our late-night parties run until the early hours—perfect for birthday celebrations, product launches, or Christmas parties where conventional venues simply won't do. We're open Wednesday through Sunday, keeping our doors closed early in the week to maintain that air of mystery. Whether you're planning an intimate gathering or taking over the entire space, we'll help you create the kind of night people still talk about years later. Just remember to keep the password to yourself.
