No, not if if you enjoy pool! Not unless you are single, have more $ than you know what to do with, and spend 24/7 in a poolroom anyway.
If pool means that much to you, make sure you have a room in your residence big enough to have a high quality commercial table (Gold Crown or a Diamond). Also, live in an area where there is a nice pool room available to frequent.
Your pool table rental $ by itself will be a small % of the total revenue. The main income producers will be the food/grill and the bar operation, which believe me is a lot of work and constant issues.
The hassle of owning and running a pool room, bar and grill is a lot of work, and most likely not profitable. This is coming from someone who has owned/operate a pool room / grill for 25 years!
Honestly if I had to do it all over again knowing what I know now, I likely would have chose something else, but at this point I’m too far along and it’s too late to turn back.
