In San Francisco, we knock on the door at Sam's Chowder House for some of the freshest street food by the bay, like a tasty Maine Lobster Roll and a perfect Shrimp Po Boy. Next stop is Houston, Texas where the Waffle Bus is delivering no-nonsense Chicken & Waffles, a Smores Waffle and even a Strawberry Irish Creme Brulee Waffle for those who dare. Then we rock up in Nashville at the Mere Bulles truck for a little taste of Southern Hospitality that includes a Macaroni and Cheese Burger and Blue Cheese Chips. Lastly it's a pizza emergency in Las Vegas, where the Engine 1 fire truck is putting out hunger one pizza at a time with their Double Stuffed Pepperoni, Barbecue Chicken and yummy dessert varieties.
