For the past fifty years, Subway has been serving pizzas and meatball sandwiches to loyal fans. While the food coming from the kitchen isn't exactly cutting-edge -- the half-thin New York style red-and-whites hit with dry oregano and the Dago Dog (Italian sausage with cheese and chiles deep-fried inside a pastry jacket) are the best bets -- it comes out tasting like a long and solid history of north Denver Italian.
