Honestly it's probably never going to be profitable. If you want to minimize your headaches and time there then alcohol and food are terrible ideas. If you just like having a place to play in your town and for the public to play, do it as cheap as possible, use the business to expense the games, keep them clean and playing well and find some kids you can trust to run the front door. It won't make much or any ever but if you enjoy having it then that may be enough to make it worth it.
