Cafe Onion Seongsu

A signature bakery cafe in Seongsu-dong, featuring a unique vintage interior from a renovated 1970s factory building and a spacious rooftop terrace. The name "Onion" doesn't mean the vegetable, but rather refers to the layered structure and delightful flavors. With excellent homemade bread, pasta, and coffee, it's considered one of the most must-visit cafes in Seoul.
