24-hour Seocho café with decaf coffee and outdoor seats: Selecto
Selecto Coffee Sinnonhyeon Branch 24 Auto Brew Cafe is a 24-hour café in Seocho, Seoul. I tried a smoked salmon sandwich and a decaf iced Americano, then checked out the spacious interior, outdoor seating, and self-service setup. A great one-stop spot for a meal and café work or study.
