The original Onion location at 8 Achasan-ro 9-gil transformed a crumbling factory into one of Seongsu's most iconic industrial-chic spaces, all exposed brick, soaring ceilings, and rusted steel frames. Specialty espresso drinks hold up to the architectural drama, and the bread and pastry program is among the best in the neighborhood. Open from 08:00 on weekdays to 22:00 nightly.
