The last two teams head back to L.A. to catch a ferry to Catalina Island. But first, they must compete as hot dog vendors in the port town of San Pedro for a travel advantage to get to their final destination. In the end, the family who sell the most are named the winner of Season 7 and receive $50,000.
Tempers flare as temperatures rise when the final three teams brave the sweltering desert heat of Palm Springs as they take on the challenge of making something sweet to eat. Then, they become "human roadside attractions" when they create attention-getting costumes before another family food truck is sent home.
Four teams remain as the competition heads inland to Santa Barbara wine country, where they take part in a challenge that involves ostriches. Later, they encounter some setbacks during a busy weekend of selling in the Danish town of Solvang, Cal.
