Review for River Rock Casino Review For River Rock Casino Google User Jan 18 '17 at 20:38 Can't comment about the room since I stayed in the River Rock Hotel. But loved the amenities. The hot tub is fun, and so is the waterslide. Just pay attention not to kick the pool floor when sliding down from the water slide. Food in the buffet and the casino are both good. Make sure to join the club to get 10% off. They also give $5 credit with the membership, which can be used at the slot machines. View full site to comment or like
