First up we're cruising to Orange County, Calif., for sizzlin' Singaporean fusion at the Chomp Chomp Truck where best-sellers include a Spicy Soft Shell Crab Sandwich with Lemongrass Vinaigrette and Japanese Sweet-Potato Chips. Next we're curbside in Toronto, Ontario, for the best barbecue in the city, at the Hogtown Smoke truck where you can get a Smoked Beef Brisket "Po' Boy" with caramelized onion and horseradish aioli and a Carolina Pulled Pork Sandwich with Root Beer Baked Beans and a cornbread doughnut. Then in Philadelphia, we're treated to mouth-watering, eclectic comfort food courtesy of the Vernalicious truck. Fan favorites include a Vietnamese Spicy Chicken Bahn Mi sandwich with Daikon Radish and Jalapenos. And finally we pull up alongside the Purple People Eatery in Miami, Fla., where two chefs are serving up a Bison Burger with truffle oil and quail's egg and a Ceviche Salad with Octopus and dragon fruit.
