Marong Karong is a dessert shop in Gongneung-dong, Seoul, specializing in thick ttungkarong macarons. It offers cheese flavors such as hwang chijeu and tiramisu, along with Earl Grey and nokcha, with fillings that are less rich. Customers take a number ticket and buy in order, with a limit of three macarons per flavor and 24 in total. The macarons use a butter-based filling, so eating more than one feels heavy.
