The pinball locations in my area seem to cater to adults more so than kids. Kids are intimidated by pinball machines and are often actually discouraged by parents who don’t want to see their $1 disappear in 30 seconds. Think more of a barcade type location with drinks, food, places that pinheads are likely to go. In my area even these types of pinball locations only survive thanks to local pinheads and especially tournament or league play. Pinball is a niche - I would think you really need to figure how you will tap into this niche in your area
