Odile refers to dancing at 'Mimi Pinson's'. 'Mimi Pinson' was a fictional character in a book by Alfred de Musset, 'Mademoiselle Mimi Pinson: Profil de grisette'. It is likely her name was appropriated for the name of a dance hall/ café. It has links to Odile's character in that Mimi Pinson was a grisette, a term used to define independent young women who were adventurous and lived only for moment.
