“Expressive dance” means any dance which, when considered in the context of the entire performance, constitutes an expression of art, theme, story or ideas, but excluding any dance such as, but not limited to, common barroom type topless dancing which, when considered in the context of the entire performance, is presented primarily as a means of displaying nudity as a sales device or for other commercial exploitation without substantial expression of theme, story or ideas, and the conduct appeals to the prurient interest, depicts sexual conduct in a patently offensive way and lacks serious literary, artistic, political or scientific value. (Ord. 743 § 10, 1996).
