What poutine is to New Hampshire, disco fries are too New Jersey. Honestly, we can't help but think that New Jersey's french fry dish was highly inspired by their state brothers to the north who both have Canada to thank for the deliciousness of combining gravy and crispy french fries. The only difference between poutine and disco fries is that poutine relies on cheese curds for that extra salty kick while melted mozzarella cheese is the added element of deliciousness for disco fries.
Several establishments throughout the Garden State claim that they are the originators of providing disco fries to the masses but many local residents would give that crown to none other than the notorious Tick Tock Diner in Clifton, New Jersey. Ironically, disco fries existed prior to the days of disco but got its name in the '70s from partygoers crashing diners after a late night of drinking and dancing.
