The fries are GREAT!!! Thick and potatoey (is that a word?).
I know these are matters of taste, and somebody likes anything. But a proper french fry can be difficult to do. It takes cooking in two stages at different temperatures. Lower to cook the potato through, and higher to make it GBD (golden brown and delicious). That can be cheated by making them very thin, or using par-boiled potatoes.
McDonalds actually pre-cooks the fries before they get to the stores, where they are cooked again. It's no accident that their fries are consistently rated the at the top.
Cutting up a potato and dropping it in a fryer is simple and efficient, but it isn't a proper french fry and can't compare to one made correctly.
