Guilty pleasure

A guilty pleasure is something, such as a film, a television program, a piece of music, or an activity that one enjoys despite understanding that it is not generally held in high regard or is seen as unusual or weird. For example, a person may secretly like a film but will admit that particular film is poorly made and/or generally seen as "not good".

It can also be used to refer to one's taste for foods that are considered to be advisable to avoid, especially for health reasons. For example, coffee, alcoholic beverages, smoking and eating a little piece of chocolate after dinner are considered by many to be guilty pleasures.
