Disco fries, similar to the poutine of Quebec, is a dish made up of french fries covered in brown gravy, on top of which cheese is melted. Although American cheese is most prevalent, cheddar and mozzarella are sometimes used. Disco fries are available almost exclusively at diners in the northeast United States, most notably New Jersey.

Many diners do not list disco fries on their menu, but the delicacy is often available upon request. Some establishments use marinara sauce instead of gravy, similar to Italian poutine, but this is relatively rare.

The relationship to disco is obscure.
