If I were ever to open my own coffee shop, I would specialize in coffee foam art, so customers could drink in art everyday. That would be the name of the shop: Drink in Art Everyday. I would encourage customers to enjoy their coffee while they sit and sketch. My shop would not keep typical coffee shop hours, because I am not a morning person.
But, alas, I'm not really all that interested in running a coffee shop. Too much business; not enough creativity.
