Food Feuds heads to North Jersey to settle a slider battle that has been brewing since the 1939 World's Fair, and Iron Chef Michael Symon is at White Manna in Hackensack and White Mana in Jersey City to decide which burger brings the beef. The buns may be bite size but this feud is a monster. In Barberton, Ohio, Eastern European immigrants have been frying up their own brand of chicken for over 70 years, and not much has changed at White House and Belgrade Gardens. Michael Symon discovers what gives the bird that extra crispy crunch and where the famous hot sauce gets its kick at the two monumental fried chicken institutions.
