You gotta pay to be at a coffee house. And sure, coffee isn't terribly expensive and most places won't kick you out even hours after you've bought your single cup of coffee, but non-Starbucks coffee shops are usually tiny and in some places hard to find.
A bookstore that also had a cafe in it. People would go there and buy a drink or whatever and read. The problem was after reading they didn't have to buy the book. I read a ton of comic books for the price of a coke back then. A library set up like this would be pretty cool.
I like it, and can it have a dedicated place to draw/create? What's the auditory experience going to be like? You're going to have to tell us more about this cafe you're 'never' going to have XD
