went to each truck to taste their signature dish and offered menu tips and financial advice. Heroes on the Half Shell paired up with Chops' Shop and many of the trucks went through lulls and high-selling periods. Challenge: As soon as they arrived in town, the teams were given shrimp and pantry staples, and told to make a signature shrimp dish to sell head to head on Fremont Street. The team who sold the most in four hours got a prime, exclusive selling spot next to the Las Vegas strip the next day (no one else could park on the strip). The winners were Mobile Moo Shu. An Oasis in the Desert (Week 3) The teams converged at a Sonic drive-thru restaurant in Phoenix and met with Tyler and Sonic's Senior Director of Culinary Innovation, Mackenzie Gibson, where they got a tasting challenge that preceded a cooking challenge. Just Wing It sneakily followed Mobile Moo Shu's online location posts and decided to park near them since they were the strongest team thus far. Victoria and Marla, from Buns N' Thighs, had to leave the competition to take care of a home business and an ailing father, respectively.

On day 2, Mobile Moo Shu and Just Wing It were parked illegally so they had to move. Challenge: Part 1 of the Sonic challenge involved a blind taste test of three specially chosen Sonic drinks. Mobile Moo Shu guessed the most flavors correctly and won. Part 2 had the teams making a dish inspired by one of five Sonic drinks: mango limeade, ocean water, cherry limeade, raspberry lemon iced tea, and strawberry lemonade.

Just Wing It were given strawberry lemonade, New England Grill were given ocean water flavor (coconut and lime), Chops' Shop were given cherry limeade. Buns N' Thighs got raspberry lemon iced tea. Later on, Tyler and Senior Director Mackenzie judged which truck utilized the drink flavors in their dish the best, and
