i've tried most of the pool halls in the Pioneer Valley, and this is my vote for the best. best tables, best maintenance, best players.
they have about 10 Brunswick 9' tables with Simonis cloth, and keep them clean and level. they also have a bunch of coinop small tables, if you're into that (i'm not). decent snacks, sound system a bit loud for my taste. $6/hour/table, open 11a-1a most days.
one of the big attractions here is the calibre of the players: many good players; it's the only room in the Valley where i haven't been asked "what's that you're playing?" when i'm shooting straight pool.
not the cheapest, but the best in every dimension.
