There are tourneys every night except Sundays. Three of the Fast Eddie's have tourneys different nights of the week. There are a ton of bar box tourneys all over the city. Too many to list.
Coach's Corner, a local bar, has a tight 9' Diamond and a couple of Diamond bar boxes. I believe their weekly tourney is on Thursday night. The place is good for some inexpensive action from late afternoon on. John Vargas, the owner, is a big sponsor and supporter of pool in SA. This is where Rob Saez hangs out when he's in town.
G Cue Billiards and Dart Supply on West Ave. just installed a 10' Diamond, a couple of 9's and a couple of Diamond 7's this last week so it's seeing a lot of action lately. Luis, the owner, is a nice guy. He'd be happy to help you with any local tourney info you need when you hit town.
