Review for Thunder Valley Casino Resort Review For Thunder Valley Casino Resort Google User Jun 19 '18 at 16:55 I only visited the the casino and the buffet and it was great. I won $88 dollars (broke even) playing the slots. They had hundreds of slot machines! And the buffet had a lot of good food. They didn't have the cheap stuff either. I went back a few days later because I enjoyed it so much. I will definitely keep adding Thunder Valley Casino to my itinerary when I visit the Sacramento area. View full site to comment or like
