Lounge J sits near the Dodu coastal road and Jeju Airport, selling Jeju Air goods, Sanrio character products, and Jeju souvenirs. The stock runs from hats and sunglasses to keyrings, postcards, phone grips, clothing, and milk sandwiches. A paid unmanned cafe on the second floor looks out over the sea, and the parking lot is large. Prices tend toward the high side, which can feel like a burden.
