Review for Osage Casino - Bartlesville Review For Big ZZ Princess Slot Hall Google User Jan 25 '18 at 13:46 An awesome day out what the plenty of history to absorb. Wouldn't recommend this to anyone with young children as they're likely to get bored and the 2-3 hours it takes to get around the castle will test the patience of most children. This is a fantastic day going it for adults View full site to comment or like
