Bemelmans Bar…as in Ludwig Bemelmans, creator of Madeline?
Yes! Ludwig Bemelmans painted a wrap-around Central Park-themed mural for the 1947 opening of the bar at The Carlyle. In exchange, he and his family lived at the hotel free of charge for a year and a half. See the murals on the Bemelmans Bar webpage.
The Carlyle began as a residential hotel, and still serves that purpose as well as being a stop for travelers. Every American president is said to have visited The Carlyle. John F. Kennedy owned an apartment there the last ten years of his life, famously sneaking Marilyn Monroe in through a series of tunnels.
