I find that if you're in an unfamiliar town the amount of vehicles in the restaurant parking lot, is a good indicator of the quality of food with-in the establishment. The locals certainly know which ones to steer clear of!
It depends really on what your food style is. The 99 is a good place if you are into classic food. McDonald's if you like salty things. And, Papa Gino's if you LOVE pizza. These are some suggestions and I hope I helped you pick a nice place to eat out on. :)
