Angel-in-us Seoul Sky is a cafe at the top of the Seoul Sky observation deck in Lotte World Tower, selling coffee and drinks. It serves visitors who come for the view and stop to quench their thirst while looking out over the open panorama. The space sits inside the observation deck and is meant for resting while taking in the Seoul Sky view, but there are no tables right at the window where you can look out. The layout makes it awkward to eat while looking directly at the view through the window.
