Fast food joints that large have hit and miss quality all over the country and location to location. Time of day matters too. But they bought fries at various times of day and picked better locations of some and worse of others. Additionally, Weissman gravitates to skinny fries because he wants crunch more I guess. I disagree with that whole heartedly. I have my own fry cutter and deep fryer and am very invested in fries.
TLDR; I don't trust Weissman with fry reviews
