Oenl is a restaurant on the first floor of the same building as Ground Seesaw Seongsu, serving brunch, pasta, and risotto. Coffee reminiscent of an American diner can be ordered with brunch menus, and the interior gets good natural light. The edit shop Small Glass is inside the store, selling plates, cups, and posters by young artists, and brand pop-ups are often held there. The surroundings extend to a red brick building and trees.
