Cafe Onion Anguk is a bakery cafe in an alley off Gye-dong-gil, Jongno-gu, that was renovated from a 100-year-old hanok (traditional Korean house). It maintains its 'ㅁ'-shaped structure with a central courtyard and a daecheongmaru (main wooden floor). The aroma of freshly baked bread and espresso fills the space every morning. Its signature Pandoro is famous for its visual of sugar powder fluttering like snow, and the salt bread and croissants are also top-notch. With many international visitors, long queues often form early in the morning, especially on weekends. It's a 3-minute walk from Anguk Station Exit 3.
