I've had both Disco Fries and
Poutine (don't judge!) and Poutine wins hands down. The fries, gravy and especially the cheese curds instead of grated cheese are just better up in Quebec, so in this case, Jersey loses... although I'm sure it's not that tragic of a loss.
But I still prefer something called CDG (Chips, Dressing and Gravy. trans: French Fries, Stuffing and Gravy) that they sell in St. John's, Nfld, Canada. It's Carbo-licious.
