The interior of Plasma 501 features red lighting. There is a dance stage downstairs, with a yellow-coloured strobe light, and a few tables that can be used for chatting. There is a stage with a drum set, a grand piano, a bass, and an acoustic guitar. There are men's and women's bathrooms, the former having a urinal and a toilet. A bar is located up a flight of stairs that are inside the club.
For a Vampire Lounge, there are many human Sims that enter and very few Vampires. The bartender may also be a human Sim, along with the bouncer at the lounge's entrance. On occasional nights, the lounge is packed - but most of the days it has very few or no Sims inside, other than employees.
When entering Plasma 501, the player can take the elevator to the vampire lounge or go to the basement floor, which contains two Altars for vampires to sleep on. There are yellow stones in the room; when followed, the stones lead to a staircase, which subsequently leads to a very small garden. A red light and a gravestone can be seen, where Lotta Greaves is buried.
There is one bouncer who guards the main entrance. To gain admittance, your Sim has to have at least one star of Celebrity Status, bribe the bouncer at least a medium amount (§50) of money, or sneak in (wait until the bouncer is distracted, then click the rope).
