James Martin continues his American Adventure with a high-octane pit stop at the world-famous Sonoma Raceway. Nestled in amongst Sonoma's vineyards, James finds out about preparations for an IndyCar season finale and gets driven around the track by Mario Andretti, one of the undoubted kings of American motorsport. James cooks trackside before visiting a new foodie Sonoma hotspot simply called Shed; after a wholesome lunch, James gets invited to Mario's nearby vineyard for wine and a chinwag.

James Martin enters the 'City of Dreams' in style while driving a vintage Porsche on his way to some of the standout foodie highlights of the series. After a visit to an incredible food market in Santa Monica, James heads to the beach to cook up a storm. He also meets a pensioner who happens to be a fitness coach, drops in on old friend and chef-to-the-stars Wolfgang Puck at his Beverly Hills restaurant CUT and the best steak in town, and finishes his visit with a bite of his favourite pizza.

James Martin begins the Texan leg of his American Adventure by visiting a place with more than a hint of Mexican spice. San Antonio was once a part of Mexico, and its influence is all around this great city. After learning how prohibition helped shape San Antonio, James uses traditional flavours and ingredients to cook his take on Mexican food in the historic market square before sampling traditional tamales and barbecoa at the hands of Johnny Hernandez, perhaps San Antonio's most famous chef.
