The Champion Cook(1932)

Le Cordon Bleu doesn't refer to a ham-and-veal delicacy, though there is plenty of ham in this Gallic comedy. The scene is a posh Parisian hotel-restaurant, which ends up a hotbed of infidelity and mistaken identity. Hotel cook Regina is romantically involved with her boss Octave, the husband of Irma. Mistaken for another woman, Irma is passionately pursued by Bernereau, whose wife gets involved with someone else's husband, whose wife gets involved with.
