Sijongilgwan is a brunch cafe in Suwon-ri, Hallim-eup, Jeju, converted from a house and operated as a no-kids zone. It serves corn-topped lattes and pancake brunches, and beer is also available. The space is divided into three rooms, and when seats are full, you leave your phone number and wait outside until you are contacted. The number of tables is small and turnover is slow, so waits tend to form.
