Review for Osage Casino - Bartlesville Review For Osage Casino - Bartlesville Google User Dec 9 '18 at 16:34 This place is only decent when there's a lot of people playing. River Spirit has the better advantage and pays out a lot better than here, even when there's not as many people. It's a shame to drive all the way out there to play the tight machines.
