I give it two thumbs up!
Keith and I had a night alone on Sunday, so we decided to drive up to Oklahoma and gamble! The place was pretty nice- and big. I think the average age was 63, but the machines were nice, the tables had good table minimums, and the people were friendly.
I didn't find a 3 credit max double-diamond machine where the diamonds move to the bar line on the end of an aisle in a highly trafficked area...but I would definitely go back!
