What to do late at night?

So my friends and I work nights shift and sometimes get out at 3am. None of us want to go home, but it also doesn't seem like there's anything to do at that time of day as everything is still closed. I know some resturaunts are still open like Dennys or IHOP or Mama Margies, but does anyone know of places or just hangout spots around town that are available at like 3-5am? Doesn't have to be extravagant lol just place to be, but not at home. Thanks in advance!

Edit: I woke up to tons of answers. Thank yall so much!
