if you wanna add some good Okla haunts (besides Meers Store) here are 5:
Esihen's Bar, 108 S 2, Okarche, Oklahoma, 73750 (they say oldest bar in the state and they say best fried chicken) (I can verify they sell fried chicken)
Ingrid's Kitchen, 3701 North Youngs Boulevard Oklahoma City, OK 73112 (I recommend this great German food, sandwiches and bakery.)
Pete's Place, 120 SW 8th Krebs, OK 74554 (local Italian food from immigrant coal miners from the turn of the last century) (several other local cafes there)
Enrique's Restaurant, The Airport, 2213 N Waverly Street, Suite 3, Ponca City, OK 74601 (perhaps one of the best Mexican restaurants in the US- fliers from all over the country stop here just for the food)
Crow Creek Tavern & Restaurant, 3534 S Peoria Ave, Tulsa, OK. (Bar & Grill in Tulsa Brookside area, fireplace and rider haunt)
