Park Jin Sung runs an odd little late-night restaurant where customers only choose which drinks they want and their appetizers are chosen by Park, who customizes the dishes to match their drinks. His goal is to provide diners with warmth and comfort through delicious food and excellent customer service. Seeing customers enjoy their food also gives him a great measure of happiness. At the urging of one of his regular customers, Park becomes the host of a new variety show called Midnight Snack Couple, which shoots him to popularity and fame. Regular customer Kim Ah Jin is a passionate PD. She usually has a smile on her face and always looks on the bright side. Her optimism is only matched by her love of food and drinking. After working hard as a crew member in production teams for many years, she finally gets her break as a PD when she convinces Park Jin Sung to become the host of her TV show.
