That is somewhat incorrect.
West end billiards was located on Westfield Ave, between Morris Ave and broad St.
Palmer billiards was never located there. It was right next door, closer to Morris Ave. Later, when Palmer closed the shop, it became some video store, like Blockbuster or something like that. it was back in 1991-1992.
And yes, Frank used to have his shop right around the corner.
As for West end. I am pretty sure it closed around 2003-2005.
