I didn't think the fries were very good, and fries are half of the menu. They seem to only cook the fries once. French fries are traditionally fried at a low temp, allowed to cool, and then re-fried at a high temperature.
The frozen fries used in other fast food places have already been cooked the 1st time before they were frozen.
I thought the fries tasted like raw potato, so you may be right. Just tasted awful.
