You can buy Donut Fries all over the country, but the 25 participating stores are limited to five markets. It'll take place at five restaurants in Boston, five in Chicago, five in Los Angeles, five in New York City, and one store each in five cities across Tennessee.
Donut Fries are a "buttery croissant style donut" coated in brown sugar. That means it's definitely not healthier than french fries, but it's technically different than french fries. That's maybe all you're looking for in breakfast dessert on a Friday.
