["On weekends or holidays, there might be a wait for the 7th floor, and there's a 2-hour usage limit, so it's a good idea to check the Catchtable app before visiting.","The 6th-floor seasonal coffee bar operates by reservation, so if you want a deep coffee experience with a professional barista, be sure to make a reservation before visiting.","The rooftop offers a truly magnificent view of the Han River and the city, so I recommend visiting on a nice day to fully enjoy the panoramic scenery."]
