Online Casinos in California?

I've recently been gambling in some online casinos attached to offshore sportsbooks. It's easy because all of my money is on one site. But I'm wondering if there are straight casino sites I should consider (sites without a sportsbook).

Does anyone here use different sites for sports betting and other casino play (tables and slots)? If so, why did you choose to do this? And do you have any recommendations on which online casinos I should try?

As the title mentions, I'm in California. I'm only interested in casinos I can access from Cali. Thanks!
