Review for Choctaw Travel Plaza - Poteau Review For Diamond Mountain Casino and Hotel Google User Feb 21 '18 at 17:04 If you aren't a smoker, don't go. You can't hardly breathe. The trash that frequently visits the casino there makes you feel very uncomfortable as the spend their free welfare money earmarked for their kids and rent on booze and cards and slots. Take the drive to Reno, NV or even Redding, CA to their Win River Casino where the air is breathable and the food is excellent. View full site to comment or like
