Im pretty sure they could hit bricktown. Good restraunts. But the price is what gets yea. I have a good buddy that works for the melting something food place. They make fondu and other wierd crap and its like 45-50 bucks a plate.
Im not sure, but the aqurium actually might have a diner near by. I havent been around in awhile. But i would definatly tell them to check out bricktown.
