Hello, @Sid1701d9!
The restaurant is player MADE but not player OWNED. I made two so my Sims could go on dates together, but none of my families ever own them.
What I HAVE noticed, however, is that the roles of Host / Hostess or one of the chef's is (for some reason) filled by a vampire. Sometimes it is one of the vampires that came with the Vampire Expansion pack but most of the time it is a randomly generated vampire. In my latest game, the Host for BAM! Flavor Town (my newest restaurant) is filled by the vampire that came with the Magic Game pack. At least I THINK he came from there because he wasn't in my game before I bought and installed that pack.
Regardless, if I am understanding your suggestion, I should delete the chef stations, save the lot, exit the lot, re-enter the lot and put down new chef stations. Yes?
