Where Can I Find Casino Parties In The Bay Area, CALI???

Hi all,
I`m looking for Casino parties , or crap parties in the bay area. They don`t necessarily have to but related to using real money to gamble, but to win prizes and such will do also.. But I dont mind if they even let u use real money to play, ha.
Im located in San Francisco and would love to visit some of these parties. Where can I find them? I tried Googling but have had no luck. Any help ? Thanks in advance.
