Debussy Sanjang is a cafe near Hanyang University that has operated since 1990, serving drip coffee, milk tea, and sandwiches, with tarot readings also available. The drink list includes drip coffee, milk tea, vin chaud, and sangria, alongside sandwiches and tteokbokki. It stays open until 2 a.m., hosts indie musician performances at times, and keeps an old guestbook on hand. The drinks and tteokbokki run sweet.
