Not so, Lalzo.....
In the case of Fast food fries, many are made thinner than others [like A&W fries or Wendy's to McD's] And as we know, bigger fries are better. Also how much grease they put in [too much is too much, but too little isn't good either] and salt you can put on yourself, right? So if that's how you see it, then all fries are perfect.
And I had QUITE forgotten about Arbies curly fries.... They beat all others, easily. [even Huckleberry's gourmet fries.]
