Let me be quite clear. I have never in my 12 years of eating Frank's had anything but the buffalo chicken pizza. It's that good. I know there is more than one location, and yes I have had them all, but Millvale is by far the best one to order from. All the employees tend to me generally nice and always approach me as soon as I walk in the door for a pickup.
The chicken is broasted (which I understand to be a type of pressure frying) so it's different than usual frying. I will say sometimes they don't put enough cheese on, but if I go twice a month, they'll get it perfect 85% of the time. And when it's perfect, it's heaven. Oh and the ranch? Beyond words.
