First up for James Cunningham is gourmet street meat at the Japadog cart in Vancouver, B.C., Canada, where he finds a lot more than the average hot dog. Next, things heat up in Miami at the Rolling Stove, a mobile truck serving up hot and spicy meals like jerk chicken. For authentic Scottish-style fish and chips, James is off to the Frying Scotsman in Portland, Oregon, and he cools things off at Coolhaus, a converted postal van in Los Angeles serving architecturally inspired ice cream sandwiches named after famous architects.

Using local and sustainably sourced ingredients, Garden State Cart in Portland, Ore., serves East Coast-Sicilian fare such as their Meatball Hero Sandwich and their popular vegetarian chickpea fritter sandwich. Led by Chef Joshua Henderson, Skillet Street Food in Seattle is a pioneer in mobile gourmet trailers, serving dishes such as sockeye salmon with succotash and their famous gourmet burger with homemade bacon jam. For a personalized falafel sandwich, Eat St. heads to Liba Falafel, a mobile food truck with a built in condiment bar in San Francisco, which is known for beginning "falafel affairs." And finally, in Houston, Texas, Oh My! Pocket Pies mobile truck serves empanada style pocket pies with comfort fillings such as chicken chile relleno.

For gourmet burgers and a side of heavy metal, Eat St. heads to Grill 'Em All, a rockin' mobile trailer in Los Angeles. Over in Austin, Texas, The Mighty Cone trailer fills tortilla cones with crispy chicken, deep fried avocado, crispy shrimps -- or a combo of your choice! Next, Chef William Pilz is on a mission to take his modern and refined Filipino cuisine into the mainstream with Hapa, his mobile food truck in San Francisco. And finally, with deep-rooted history in Miami, Florida's seafood and restaurant industry, it is no surprise that the Fish Box mobile truck, serving Cuban-style seafood dishes and seafood sandwiches, is such a "rolling" success.
