A small, clean shop that used to be one of the Adult Superstore chain, but has since changed its name to Flick.
There are a few DVD previewing booths, which cost $8 for up to 4 hours, but most of the store is just a DVD/magazine/ novelty shop. For its tiny size, it is surprisingly well-stocked, and even has a decent sized selection of fetish paraphernalia.
This shop is conveniently located right on the Las Vegas Strip, between wedding chapels, and across the street from uber-ghetto nude club Talk of the Town. So there are other options in the neighborhood, if you get tired of jerking off!
