Re: what do you think?
It depends on what kind of place you looking for. If you're looking to have a relaxing place to chill you should have soft music and low lighting, ect.
But if you want it to be a college hang out sorta place, make sure everone in the place will be able to talk to everyone else, so don't have one section secluded from the other. Make it really social. And have music to match that feeling.
No matter what you do, have comfy chairs, good hookahs and good/reliable shisha.
