Josh Denny arrives in Jacksonville to tackle the biggest meals in Florida's biggest city. His first stop is Beachside Restaurant and Seafood Market for the Sea Monster, a netting of five types of seafood cooked three different ways, then rolled into a grilled burrito. Later, Black Sheep gets ridiculous with a five-foot long baguette stuffed with ground duck breast and a half-dozen veggie toppings. Finally, Gas Full Service Restaurant pumps out the Full Tank, a three-pound sandwich.
