Review for Thunder Valley Casino Resort Review For Thunder Valley Casino Resort Google User Jan 14 '17 at 21:38 My aunt won over $2,000 playing the slots. She kept playing and lost a lot of it but still left with over $500 in winnings. We ate at the buffet for brunch. The service and the variety of foods were wonderful, although I can't say that I really liked the taste of many of the menu items. View full site to comment or like
