I usually try to stay away from the mega-coliseum chains, but I was in Tulsa this past Saturday and I had heard some good things about the fries at the BOK Center so I popped in.
$3.50 for about 30 good-sized fries. Straight out of a bag, but crisp, hot and surprisingly delicious! I tasted a hint of popcorn oil, so I figure some of it falls into the fry oil or something. $3.50 is kinda steep, but you have to expect a gouge at an arena.
Extra points for the old school fry cup. 7 out of 10.
