Things to do at night?

Hey guys, been living here for over 25 years now. I think I have done majority of things that you can in Bangkok, however I just wanna know if there are any new things, or hidden bars, local activites that are not too famous but I can go try it out with my friends.

We are all in our mid twenties, and don't mind anything to be honest. Could be a chill vibe, some activity, exploring, rooftop. I just wanna know if there any other things that you guys have tried and can suggest :)
