An option is to find a Panera Bread near you with a VIP room, then book that space. I do that with my Friday night stitch group (am going there tonight, actually) and we have a great time. We do need to purchase a meal while we're there, but we have also brought snacks in sporadically and no one yells at us. As a bonus, we are there from 3 PM until the place closes, and no one tries to kick us out.
Your local library may also have a community room that you could use for free or for a small donation to the library.
