Do you remember till about 12 or 14 years ago when their fries were good? They changed them and they've never been as good since.
I used to eat there two to three times a week for lunch mainly because of the fries.
They switched and the only time I go there now is if I can find a bag of potato chips someplace before I go and take them in with me.
If they ask me if I want fries with my burger I ask if they are still serving the batter-covered-tastes-like-cardboard fries. When they say yes, I point to the chips and say that's why I brought these.
