Glu Glu is a small dessert cafe near Samseong Station in Seoul that serves southern Spanish-style porras and espresso. The thick porras are dusted heavily with cinnamon, crisp outside and moist inside, and eaten dipped in a thin dark chocolate sauce. Seating is self-service, with orders placed after finding a seat, and the seats are bar-style, so conversation is uncomfortable for groups of four or more. The chocolate dipping sauce is thin.
