Great Slates in Cambridge is about 45 min from OC and is owned by John Moody. I don't know if John gambles anymore but I do know that he used to be a good player and still has a good game even though he's a business man, husband, and father now. Both he & and his son play in the US Open each yr. If John Sr. doesn't gamble, John Jr. might. That's the closest possible action and pool room near OC that I know of.
