Review for River Rock Casino Review For River Rock Casino Google User Mar 5 '17 at 20:42 We had the Weekend Seafood Buffet here for $39.95. It was OK nothing special to mention here - frozen freeze dried crab. The shrimp were nice and they have a few other choices like roasted beef tenderloin, salad bar, and a few sushi/sashimi items. The table service was good except that it took a long time to line up, pay and get a table - even though half the tables were empty. View full site to comment or like
