Incheon National Maritime High School

Idol singer Hyo Jung, the leader of Oh My Girl, joins to help the catering crew this time. Hyo Jung and the Backpacker chefs go to Incheon National Maritime High School, where Master Paik visited once 5 years ago, to cook for 230 students who are picky with food. Will they be able to turn food that the students dislike into their favorite food?
