Lowkey Seongsu 로우키 성수

A specialty coffee landmark that has anchored Seongsu-dong since 2010, often ranked alongside Center Coffee as the neighborhood's top two. Tell the barista your flavor preferences and they will select and recommend a bean, then pour each cup by hand with obvious devotion. Espresso comes with three bean choices, and the pour-over lineup cleanly articulates origin-specific notes that evolve as the cup cools. The first floor has an unusual layout - sofas wrapping around two triangular tables - and a hidden basement level offers extra seating that many visitors miss. The donuts draw nearly as much praise as the coffee itself.
