"Open for: Early breakfast through dinner Price range: $ Opened in 2016, Cafe Onion revolutionized the Seoul cafe scene with its first location in a converted factory in Seongsu, signaling the beginning of the former industrial zone’s transformation into a trendy hub filled with fashion brands and pop-up stores. Each of its four locations occupies a unique historic building, but the third branch in Anguk stands out for its stunning renovation of a century-old hanok. Combining modern design with traditional Korean aesthetics, the cafe offers a serene escape with expertly brewed coffee from house-roasted beans and a selection of freshly baked pastries. Vibe check: Takeout lines tend to be shorter, but for the best experience, wait for a seat inside." - Matty Kim
