Hangang Espresso is a small cafe between Mangwon Market and the Han River in Seoul that focuses on espresso. Its summer menu includes citrus espresso, watermelon bingsu, and a citrus slush, with sparkling water served to clear the palate. The shop has seating for two or three people and window seats, along with instructions on how to drink the espresso. The seating is tight, so a wait forms on weekends.
