Cozy, Quiet Spots to hang out in that are open late?

Are there any cafes or cozy bars that are not so full and loud that are open till very late and that you can hang out and relax and unwind? My ideal fantasy would be a nice cozy cafe with Jazz music and comfy seating. I know Düsseldorf isn’t really the city that never sleeps and options will be very limited but any suggestions would do.
