The poolroom slump seems to be coming to an end with more new rooms opening in the last year then in the prior ten years. For the naysayers it can be done and you don't have to own the building. There is lots of vacant space in industrial areas, and it's a buyers/renters market. You don't have to be on a main street! Build it and they will come!
There are beautiful and successful poolrooms operating all over the country. Maybe not nearly as many as before, but they are out there. And there's room for more. If I was a younger man I would do it again right now! The magic formula is no different than before. Give the people what they want for a fair price and they will come. Good music, sports on TV, nice pool tables, some other games like foosball, darts etc., good pizza and other finger food, beer and wine is fine. Work hard, make money. What's wrong with that?
Nobody wants to stay cooped up in their house playing video games and watching netflix day and night. Give them a nice place to go and have a good time, then watch what happens.
One more thing that I noticed in my previous rooms, where I had both big tables and barboxes. Even amateurs preferred playing on the real pool tables. The barboxes were more for the beer drinkers and for league players.
