Review for River Spirit Casino Review For River Spirit Casino Google User Sep 20 '17 at 22:58 With the exception of the Buttermilk Pie and the salad bar, the buffet is awful here. The casino floor is huge. Nice center bar. The win percentage is simply awful here. It seems that the guests are still laying for the Margaritaville addition, so the slot machines are cranked down tight. Big wins and jackpots are few and far between. I used to go to River Spirit all the time because I would typically find a few machines that were paying. Now it is just depressing walking through and seeing no smiles on the guests faces and rarely hearing any bells or big payouts. View full site to comment or like
