Mucho Ultima in Manhattan Beach, Calif., is looking for a new executive chef to help re-brand it as a destination restaurant. Anne Burrell brings in four chefs. First, she tests their knowledge of Mexican chiles, then the chefs are tasked to reinvent the taco. The two chefs that remain are each handed the keys to the restaurant for one dinner service. One chef struggles to keep pace in the kitchen while the other runs out of ingredients in service. Only one gets the job and becomes Mucho's next executive chef.
