Choctaw Durant has a great poker room. Located on the second flood around the center of the casino, its smoke free room is a nice place to play. The game of choice is BY FAR $1-$2 no limit hold em here, but every once in awhile you can find a different game.
There Saturday tournament is a great option. At the time of this review, their $10k guarantee tournament with a $180 buy in ($20 rake) is a deep stack with a great structure and low rake. I highly recommend it if you have all day to play.
Choctaw usually holds a main tournament series twice a year (WSOP, CardPlayer, WPT etc) and when they have a quarter of the year that they don't have one, they usually run their own, which is also done quite well. These are great additions to an already great place to play, and the cash games are definitely hoping and have more options during these high times.
All in all, great room especially on the weekends. It can be hard to find a game going in non peak times, but the casino does a great job of running the room.
