Review for Treasure Island Resort & Casino Review For Thunder Valley Casino Resort Google User Jan 2 '18 at 2:13 My wife and I go to Thunder Valley Casino Resort to have a drink and an appetizer at one of their several bars. Sometimes we will eat at one of their restaurants or at their buffet. All are delicious and we recommend them. Occasionally we will try the penney slot machines and have actually done very well a few times, but it is mostly for fun and entertainment. Thunder Valley Casino is a lot of fun for the right reasons! View full site to comment or like
