The Ambassador Hotel was a hotel in Los Angeles, California. Designed by architect Myron Hunt, the Ambassador Hotel formally opened to the public on January 1, 1921. Later renovations by architect Paul Williams were made to the hotel in the late 1940s. It was also home to the Cocoanut Grove nightclub, a premier Los Angeles night spot for decades; host to six Oscar ceremonies and to every United States President from Herbert Hoover to Richard Nixon.
