Quiet hangout spot recommendations?

I'm hoping someone will have some ideas for me, because I have no idea what to look for.

I'm trying to find some place, preferably in southeast Broward or Northeast Miami-Dade, where my friends and I (anywhere from 2 to 10 of us) can get together for a relaxing, chill kind of get together. Something where we could just sit together and read, do arts and crafts, have conversation if we wanted, etc. Because of the heat and possibility of rain, it would obviously have to be indoors.

I have already checked out the local Broward County libraries; all of the spaces (outside of study rooms, which you cannot reserve) have fees associated with them. And I would like to be able to have the option of snacks and drinks, but without the pressure of having to do this kind of thing in a restaurant, which would obviously be noisier and have more pressure to buy food and drinks.

Does anyone have any ideas where I might find some place like this? Before anyone suggests it, no, I can't host this at my home (much as I would like to), for reasons I won't get into here.
