Josh Denny is in search of the most titanic Thanksgiving dishes! In New York City, David Burke Kitchen puts the turducken to shame with the Piecaken: layered pecan and pumpkin pies, plus a whole spice pound cake and an upside-down apple pie. Krave It in Bayside, N.Y. knocks it out of the park with The Cran-Slam, a 26-inch pizza covered in turkey, marshmallows, yams, cranberry sauce, homemade stuffing and gravy. Then, the Square Pub in Decatur, Ga. gives the turkey dinner an upgrade with The Gobbler, a foot-tall sandwich stuffed with a turkey burger patty and topped with mashed potatoes, cranberry sauce, stuffing and green bean casserole.
