I think McDonald's, Burger King & Jack in the Box are tied.
In the UK, Burger King is by far the best, but I believe that's not the case elsewhere.
I wouldn't have a clue.
I don't like fries, but hubby likes Wendy's.
I think only 2 of those are major outside of the US, and even in GA I've never seen a 'Jack in the box'<br />
But KFC's chips are ****
None of those. They all make those skinny fries that get cold before you get them to the table. Arby's makes good fries, and great onion petals.
I prefer Wendy's myself. Carl's Jr. and Burger King aren't bad, either.
