Ppeoltteok Nakji is a nakji restaurant in Jeju that serves nakji bokkeum and nakgopssae. The signature nakji bokkeum coats chewy octopus in a spicy seasoning without oil or artificial smoke flavor. A live octopus tank sits at the entrance, and the pollack soup is refilled from a warm insulated container, with side dishes also available for refills. If you are sensitive to spicy food, take care even with the regular spice level.
