This was the place we went to in the city to (window) shop, called Joongang-ro. And it is located underground. Basically, this was the hub for (1) beauty and skincare products (2) fashion related items and accessories. Hence, there was nothing (or not much) that I could buy here. As if I really shop in the first place.
So that was the end of the first day exploration of Jeju City. The city tour was already completed, and we would be venturing to the other parts of the island for the other two days.
