Order the cloud-shaped tiramisu, moist with cream that stays on the right side of sweet, alongside the Vienna coffee the roaster is best known for. The Hannam location sits on a quiet side street near Itaewon, with a stark dark exterior opening into a pure white interior of around ten tables. Expect a queue at peak hours and a steady flow of takeaway orders. Milestone roasts its own beans and runs a second branch in Sinsa-dong off Garosugil, but Hannam is the one most locals will send you to first.
