"If you’re looking for a spot that hits the nail on the head with classic diner vibes and even better food, the OK Diner is it. ​Me and the wife ate here for lunch and was thoroughly impressed. The biscuits and gravy were absolutely delicious, the sausage gravy had the perfect consistency and that rich, peppery flavor you only get from a kitchen that knows what they’re doing. ​A surprising highlight for me was the hash puppies. They were incredibly tasty, perfectly fried with a great golden crunch on the outside and soft on the inside. It’s rare to find a place that nails both the breakfast staples and the savory sides so well. ​Great atmosphere, friendly service, and food. I’ll definitely be back!"

"Great experience and really great food. It is a shame the airport is using ADSB data to charge pilots fees—literally going to make a great place like this go out of business and keep people from flying in!!! That being said, by all means phenomenal food and service, they were busy but got us seated quickly and food came out shortly after we ordered. The onion burger was possibly better than I was told it would be!! The chili and green chili stew were both great and just make me wish it wasn’t 100° and I’d have had more!"

"Our breakfast was hot and delicious! Loved the homemade biscuits. Our server and all staff was nice and friendly. Our waitress took good care of us. This diner is inside of Norman's airport lobby which is pretty cool. Nice atmosphere, and clean. We will be going back for sure."

"Hearty servings. Knock you socks off flavor. Servers who take care of you like family. Oh my goodness good. Never had a breakfast that tasted so this good and lasted well past lunch. Five stars across the boards is an understatement."

"Breakfast was delishes and service was great even after the long wait and being super busy. Will definitely go again for lunch sometime."
