23. Sweet Potato Fries

Chain: White Castle
Introduced: 2008 

Some chains do fries so well, you wouldn't ever dream of changing them. This forces other chains have to get creative, because they're not going to beat McDonald's or Nathan's at their own game. (Fast Food Truth: Recognize your lane, then do everything humanly possible within that lane to explode the hearts and minds of your patrons.)

White Castle dominates mini-burgers, but the fry game was never worth a damn. Then they said fuck regular potatoes and switched to the creamy orange sweet potato. Whoa. #RESPECT
