Can’t speak on if any are open now, but:
I lived in OKC last year for a few months and played at Riverwind and New Castle. All table games have an ante per state law, some agreement between the tribes and the state. It’s $0.50 per hand below $100, $1 per hand $100 and up. I used to play $99.50 per hand to kill the house edge as much as possible. If you are a counter looking for an edge and good rules, you won’t be happy in OK. For recreational play, it’s not bad.
