DC night scene is wack af. Nothing like the South or Atl. DC has changed so much since when I first moved there in the early 2000s.
You best bet it to go to some happy hours and try to meet some cool chicks to show you around. Go out to Maryland, good/real people out there, even Virginia is realer than DC nowadays.
You go to those place named above, you're going to see a lot of fine women, mostly in small groupies, a few dancing to themselves. More people taking selfies and pics pretending to be having the time of their lives for IG, then go back to standing around. You going to see a lot girls facing the VIP section. Dudes too.
I hope you're on the right side of the velvet ropes my boy, or you're going to need a prayer to come up.
