I was at a pool room in Mountain View roughly 10 years ago. Was that the California Billiard Club? It was a really nice place with a bunch of tables and a 12' snooker table next to a really tasty kitchen .So far as I know, there is no pool hall in Mountain View. Both Shoreline and California Billiards are long gone. There are a couple in Sunnyvale including a new one that used to be Santa Clara Billiards.
I just looked up pool halls in that area and I see a place in Fremont:
40510 Albrae Street Fremont, CA 94538
