I cant tell you whats the best but the worst has to be Wings Diner. It is the definition of what a restaurant shouldn't be. The guy at the register didnt say a word to us, just rang it up and took my card. After that, we than proceded to the buffet where there were Styrofoam plates. I mean seriously, I know its easier just to throw them away but if you pay 15 bucks, glass would be nice, even plastic would do.
The food was either out, or dried out. The selection was horrible, and the utensils and condiments were way off to the side. The cups were really small making you have to get up and refill it constantly. There was no music to speak of, and the TV's were on something like Sportscenter which is pretty boring w/o sound.
The only credit I can give it, outside of the buffet area, the place was pretty clean.
As someone said before, the KI parking lot at lunch time is more like a tailgate party outside of a football game, I have even seen people go as far as to bring mini grills and have a cookout.
