Pilot's Cotton Tree Bar, just past Treehouse has a pool table and big bar. Plus nice people. Can't speak to the quality of the table but I just noticed they have a pool table (maybe more than one?). It located is more roadside but you can easily access it from the beach if you look for the sign around Aunties/Treehouse/Normas. With so many choices, why not a pool table crawl of Negril? Happy playing!
