The Red Oak Steakhouse is part of the Downstream Casino in Quapaw, OK. Very much off the beaten path, though only a few hundred meters off Interstate 44 where Oklahoma, Missouri, and Kansas all meet.
It is absolutely the best steakhouse in the area. The next closest steakhouse of similar caliber would be either Oklahoma City or Kansas City.
The Martinis are also very good. The stems are kept in the refrigerator, they’re mixed perfectly & amply and served promptly. Their gin selection in pretty sparse but they do have my favorite: Bombay Sapphire. The barkeep is quite friendly and will be happy to regale you with the history of the Bar, the Casino, and the Quapaw tribe.
If you find yourself in this part of the country and hungry, then definitely stop in for the steak. Get a Martini too, they’re good. It will be worth the side trip off the freeway. The Red Oak gets one stem: 
For selection the Red Oak Steakhouse gets a C-. Their Gin selection is pretty short with Bombay Sapphire, Tanqueray, Tanqueray 10, and Hendricks.
