Tteulan is a hanok tea house in the alleys of Ikseon-dong, Seoul, serving traditional teas with rice cakes and bingsu. The teas include daechu cha and ssanghwa cha, paired with old-style patbingsu and a rice cake assortment. The small shop is a converted hanok where Korean instrumental music plays and the floor is heated. When customers gather, the narrow interior gets crowded.
