W.O.W. -- we begin at the Wonderlicious On Wheels truck in Atlanta whose South American inspired snacks are the talk of the town. Smoked pork arepas, sauteed shrimp cakes and a knock out kwanza bowl will have you saying "wow," too. Next is a truly beefed up menu at Hoss' Loaded Burgers in Nashville, where cheese stuffed, grass fed burgers or a vegan patty are driving the locals crazy with delight; gouda, cheddar and blue cheese infusions help seal the deal. Then it's time for some big, bad, gourmet Italian comfort food at The Tasting Spoon truck in Orange County, Calif., such as crispy buttermilk marinated calamari, arancini and even a foie gras slider. Last stop is at the Devilicious truck in San Diego, food so good, it's bad; a butter poached lobster grilled cheese sandwich, chili cheddar stuffed jalapenos and spicy tuna nachos will satisfy the most hellish of appetites.
