They showed a bar in the trailer. The one with the pool table. So if they have that, I am sure they have those "nightclubs" as well. It is a typical trope to have in a Cyberpunk game cause it allows for music and showing characters and even have maybe cool missions taking place in them.
All the previews mentioned impressive crowds CDPR is able to pack into Night City, so I hope that with this technology we can have some impressive club scenes in the game, with 100s of people, kitsch-n-punk fashion, lights etc.
If the game does have an online MMORPG version-
-Musicians/bands/DJs for example to be guests in the night clubs see Second Life, Anarchy Online.
-Unique Night clubs and bars
.Catered to certain music styles over all or by night.
.Interaction within them- talk with NPCs, motions of drinking(even play games darts or pool). Being able to dance with different styles.
