Sojeokdu Seongsu is a cafe in Seongsu, Seoul, that sells patbingsu and patppang made with domestic red beans boiled in-house. The patbingsu tops milk ice with a firm, slightly coarse red bean paste that keeps whole beans and finishes with a cherry. Danpatjuk is available for takeout, and ruibos tea is served as a dessert in a small pot. The space is small, so conversations at other tables carry.
