I rarely go to chain restaurants, recently while at the Tulsa airport I had a 1 - 1/2 hours to kill. The food court was nice, has a national chain sandwich shop and pizza place that are good. Since I had the time I opted to go to the one restaurant offered with wait staff etc. The service was awful, the wait staff was either having a bad day or just don't care all the time. A table next to me of 4 business men waited over 15 minutes just to give their drink order and the restaurant was not busy. The chicken dish I ordered consisted of a very flat, hard and dry chicken breast, with a melted cheese sauce that was so over-cooked it turned into a thick cheese oil that overpowered the whole meal.
In a nut shell......stick with the self service food court.......you will be a lot less disappointed.
