During the day, Euljiro Alley is filled with the sound of busy printing presses, but at night, secret LP bars open their doors along the narrow stairs. Retro music from old turntables blends with Euljiro's unique vintage sensibility, conveying a distinctive energetic atmosphere where Seoul's past and present intersect. I'm writing this to introduce Korea's unique alley culture (Hipjiro) to foreign friends. Once it's well-developed through a circle of feedback, it seems like it will become a wonderful Seoul guide for foreigners.
