Wendy’s reinvented Hot & Crispy Fries are made with natural-cut, real potatoes that are lightly battered to ensure maximum crispiness and heat retention. And keep in mind, thanks to Wendy’s Hot & Crispy Guarantee, if your fries aren’t hot and crispy when you receive them, Wendy’s will replace them, no questions asked.

National Fast Food Day is celebrated annually on November 16.
