Bongkkeurang is a handmade burger shop on a roadside on Udo, Jeju, selling rainbow burgers, black burgers and peanut burgers. The black burger and peanut burger are the signature items, and one burger is enough to share between two people. Outdoor tables look out over the Udo sea and Seongsan Ilchulbong, and the inside of the shop is small. There is one toilet behind the building and no toilet paper.
