GML Coffee

GML sits on the third floor of a building in Hannam-dong, above a run of fashion storefronts, and treats its bean list less like a menu and less like a curated edit than a working library, with more than two dozen filter options documented at once. The name stands for good materials for life, and the sleek concrete room backs that up with sourcing from international names like Scott Rao's Prodigal and Amsterdam's Dak alongside Korean roaster Cospir.
The signature pour is a milk brewed coffee steeped for ten hours or more, served across what the shop calls flight lanes so a visitor can taste several origins side by side. An elevator serves the building, there is a terrace for outdoor seating, and the shop is dog friendly, open every day with no listed closing days.
