I wanna be just like a king
Take my picture by the pool
Cause I'm the next big thing
Beverly Hills... That's where I want to be!"
Beverly Hills is such an iconic place that just putting that in the title of a work is a selling point on its own. Just slap the words "Beverly Hills" in the title and make the city your setting, and you have half the work already made.
For many, the city has become synonymous with a collection of Rich People stereotypes: wealth, superficiality, frivolity, etc, so using the name helps make titles seem High Concept. There are richer and bitchier areas than Beverly Hills, but only Las Vegas rivals it as an icon of excess.
