Chefs vs. City is an American television show that aired on Food Network for two seasons from 2009 to 2010.
At each stop, both teams have to complete a certain food-related task before they receive a new dossier and advance to the next contest.
The first five season 2 episodes featured Chris and Aaron against fellow Food Network stars, who acted as the "City" representatives.
In 2014, Cosentino gave a talk at the MAD Symposium about how he regretted participating in the series.
Most notably, he had gotten third-degree alkaline burns on his stomach lining as a result of the eating challenges, which he said took him five years to recover from, during which time he had to carefully monitor his diet.
