Josh Denny heads to Detroit. Stache International serves up the Big Dawg, 3 pounds of house-smoked bologna in a 2-foot long bun topped with cheese, caramelized onions and bacon. A Latin American classic gets supersized at Garrido's Bistro and Pastry, where a hubcap-size arepa called The Punisher is stuffed with 15 pounds of pulled beef, chicken, avocado, plantains and cheese. Finally, Pie-Sci Pizza rolls out Pizzagna, a pizza topped with sausage, pepperoni and two pans of lasagna.
