Another one of those hidden gems in the industrial Euljiro area, you must navigate back alleys without signs to find Coffee Hanyakbang. Once inside, you’ll furniture from an era of a bygone area of a traditional Korean pharmacy (hanyak means Korean medicine). They specialize in drip coffee, and they have desserts as well. The cafe itself is small, but they have a space immediately across the alley where you can bring your drinks to sit down and even buy some desserts. Sit here and enjoy the jazz music with the beautiful furniture, knowing that you’re in one of the best secret cafes in Seoul.
