Review for St. Jo Frontier Casino Review For St. Jo Frontier Casino Google User Oct 16 '16 at 19:20 The buffet is okey. Eating Fridays & Saturdays is good in the evening but a little expensive. Winnings & entertainment is poor. Wish you luck and please be responsible. Spending more than $30 to $100 does not mean you will win. I can win twice a month $300 to $1000 with lors of entertainments at others casinos spending at least $100 a month total. I have never won any jackpots here Frontier casino since 2010.
