Hi There!! It got a bit frustrating for me to unsuccessfully try finding the title of a horror film about vampires I saw many years ago. I remember a scene of a strange man who munches on insects while greeting prospect "customers" at the entrance of an equally strange night club that hides a monstrous vampire creature, which takes the form of a bizarre lady, who dances around a statue with suggestive movements to attract his "preys". A group of teens slowly discover the lethal truth behind that club after one young men's corpse is thrown into a garbage recipient out of the building. Any help is strongly appreciated.

Vamp (1986)
Starring Chris Makepeace, Sandy Baron, Robert Rusler, Dedee Pfeiffer
IMDb synopsis:
Two fraternity pledges go to a sleazy bar looking for strippers to entertain their college friends. They have problems with transportation, biker gangs, and, worst of all, the staff of the bar, all of whom seem to be vampires, with Grace Jones playing the head vampire, an exotic dancer.

You're welcome! It's definitely a memorable, off-the-wall, very gory dark comedy with an interesting cast. Grace Jones is amazing in this!
