Lucky's Puccias in Austin, Texas, is our first course featuring yummy Italian sandwiches like their Hot Pastrami and Puccia Contadina stuffed with turkey provolone, arugula, tomato and a housemade olive tapenade. Then we make a beeline to the Honey Pot truck in Portland, Ore., for some sweet and savory pies. A trip to San Francisco follows where we dine out at the Phat Thai truck, sampling authentic Pad Thai, Som Tum Salad and Pad Kee Mao also known as "Drunken Noodles," a perfect hangover recipe, allegedly. Finally, it's all aboard Puckett's Trolley in Nashville for some Southern-style comfort food. Serving Shrimp and Grits Hush Puppies, Brisket Chimichanga and Catfish Tacos, this is definitely one streetcar named desire.
