Nightclub

Nightclubs are a lot assignement in The Sims 4. Nightclubs, as their name hints, are most active at night, with more Sims visiting it. It's different from the Bar and the Lounge by the fact Sims tend to dance more than drink or chat in it. There is only one pre-made nightclub in the base game, but more can be created or imported through the Gallery.

The Blue Velvet
The Blue Velvet is the only Nightclub in the base game, and is located in Willow Creek. It has 2 floors. The first floor has a bar, a piano, and a Venue Retro speaker, along with a couple of seating places. The second floor has 2 bathrooms and a couple of paintings. It cannot be converted to a Lounge, since it lacks 2 loveseats, nor it can be a Bar, since it lacks a TV.
