Ttungbo Ajeossi is a Korean restaurant near Jeoji in Jeju that serves hairtail gui set meals and braised mackerel. The hairtail is grilled as if fried in oil, crisp outside and moist inside, and comes with sea urchin seaweed soup and side dishes. It opens for breakfast, and a number ticket is needed to wait, with lines forming even before 11:30 AM. There is no parking lot, so parking on the shoulder of the road is required.
