Thick french fries are not fast food! But they are great slow food
when I go to a fancy restaurant like “Denny”s”! hehehe...

If we’re talking about wedge fries, then yes they are restaurant fries.
I’m talking about fries that are square cut, but they are about 2.0 times the width (on a side) of the McDonald’s fries.
You can find them at other fast food places, and some small stands have them.
