Cafe Hallasan sits directly in front of Sehwa Beach in Jeju, where it serves carrot cake, carrot juice, and coffee with a view of the sea. The menu also includes hallabong hot tea and decaf americano, and the interior is decorated with vintage objects and plants. The main building and an annex are separate, and the annex is used by guests with cat allergies. There is no dedicated parking lot, so cars must be parked on the narrow roads nearby.
