There were a bunch of fast-food polls on here a couple months ago, but a search didn’t find a thread asking simply about the quality of the fries.
My vote goes to Checkers, simply because they’re the only fries I can eat without feeling the need to add anything to them - they’re perfect as served.
5 Guys gets special credit for giving you an entire paper bag full of fries when you order the small. I don’t think anybody has EVER ordered the large.
Also some credit to KFC - their fries are the only edible thing they serve.
Worst goes to Burger King - are those warts or zits covering the breading?
