Review for Osage Casino - Bartlesville Review For Osage Casino - Bartlesville Google User Feb 3 '19 at 15:54 We occasionally make the trip to Osage Casino in Bartlesville on a Friday evening for their buffet because they offer crab legs. If it wasn't for the crab legs we wouldn't find ourselves traveling an hour drive from the Coweta. The buffet is much smaller than Hard Rock or River Spirits, but neither of bigger casinos offer crab anymore (I believe River Spirit does offer it for an up charge per a lb). Overall, we have always enjoyed our visits, at least 3 trips in the past 5 months. My wife finds a game to play before or after we eat, so she is happy which makes me happy.
