Josh Denny lets the good times roll, hunting down New Orleans' most massive meals. Dat Dog unchains its Datzilla, made of three Louisiana-style hotdogs -- alligator, crawfish and hot sausage -- loaded into an enormous bun and covered in French fries. The historic Parkway Bakery and Tavern's Bayou Beast makes a monster-sized "poor boy" sandwich out of two 32-inch French bread rolls filled with pot roast, deep-fried shrimp and alligator sausage. Not to be outdone, The Big Cheezy wheels out its Daddy Mac, a behemoth of roast beef and bacon that overflows buns made from two mac and cheese sandwiches!
