At Mugga Dosirak in South Korea, a team of three chefs and 15 staff members cook and package 10,000 lunch boxes every week by hand, and sell around 400,000 lunch boxes every year. We visited their kitchen to see how they prepare these meals in such big batches. Editor's Note: At 9:12, this video incorrectly states that each lunchbox costs 30,000 won. They actually cost 7,000 won. Insider regrets this error.
