The Monster Club (1981) on Netflix

A fictionalized version of author R. Chetwynd-Hayes (John Carradine) is approached on a London city street by a strange man (Vincent Price) who turns out to be a starving vampire named Eramus. Eramus bites the writer, and in gratitude for the small "donation", takes his (basically unharmed but bewildered) victim to the Titular Club, which is a covert gathering place for a multitude of supernatural creatures. In between the club's unique music and dance performances, Eramus introduces three stories about his fellow creatures of the night.
