Specialty of the Korean Service Area

Hello, these are walnut buns I tried at the Eonyang Service Area on the Gyeongbu Expressway, heading from Busan to the World Heritage city of Gyeongju. Walnut buns are a specialty of Korean expressways and are available at every service area. Approximately eight 160-gram buns cost 2000 won. Walnut buns are also available at Busan International Market.
