Haegwang Sikdang is a Korean restaurant on Udo in Jeju that serves bomaltot kalguksu and sea urchin bibimbap. The bomal kalguksu is cooked in a jeongol pot to match the number of diners, and the noodles are handmade fresh every evening. Perilla seed powder sits on each table so diners can add it to taste, and after the kalguksu, fried rice can be ordered with the remaining broth. Solo diners are welcome.
