The final two teams head back to Los Angeles, where Tyler Florence welcomes them to the historic Pueblo de Los Angeles, the epicenter of LA's Mexican heritage and culture. He introduces Bricia Lopez, co-owner of James Beard-award winning restaurant Guelaguetza, and they explain the Mexican ingredients and flavors the trucks will be using in their final challenge: chayote and habanero peppers. Both trucks pull out all the stops for the win, but only one team is awarded the $50,000 grand prize.
