Yum Yum is a handmade burger shop on Garosu-gil in Sinsa-dong that pairs patties with buns. The menu includes an egg bulgogi burger, an avocado burger, and a cheese burger with both cheddar and mozzarella, and the fries come as either sticks or hash browns. Drinks can be refilled freely, and mac and cheese is also on the menu. The chicken tenders have an odd aroma and taste ordinary.
