Glyn is a coffee shop in the alley next to Poigeunrin Park in Gaepo-dong, Seoul, serving hand drip coffee and lattes. It selects good beans and considers water and dry weather when brewing, keeping the taste of each cup consistent. The cafe is open on both sides, with one side leading to the alley and the other to the walking path of Poigeunrin Park. Iced Americano has acidity, and decaf latte and affogato can also be ordered.
