Bemelmans Bar is a cocktail lounge and piano bar in the Carlyle Hotel, on the Upper East Side in Manhattan, New York City. The bar opened in the 1940s, serving wealthy Upper East Siders and numerous celebrities. Bemelmans has distinctive Art Deco decor, including murals of Madeline painted by Ludwig Bemelmans, author and illustrator of Madeline. It has been known for multiple drinks, though in recent years it is best known for its martinis, often served very dirty.
