I agree with Don and Brett's posts, above. Be consistent. Are you looking for a place for musicians to play? Or, are you going to be in the business of selling coffee, with music as an incentive to bring in customers? The Chicago suburbs had a ton of coffeehouses that started in the mid-to-late '90's. Many had musicians playing for tips. All these places are closed now. I used to tag along when my significant other played at some of these places. In one place, the sound system was set up by the front door. I often saw people walk up to the coffeehouse, see there were performers playing, and walk away. Being clear about what you want is very important. If you're running a business, ground rent is bound to be high, so you need to sell a lot of coffee and treats to keep open. If you're in a free location (church basement, community center) you don't have an over head to worry about and you can pursue making a place for musicians to gather. Good luck.
