The house pour is the Camel Coffee, a strong espresso through fresh cream on a caramel-like syrup base, served iced and read as a sweetened latte with bite. Pair it with the ang butter, a red-bean and butter bun, or a kouign-amann. The M.S.G.R., a roasted-grain milk drink, is the alternative if espresso is not the move. The Seongsu room runs French-vintage, mismatched chairs, retro brown carpet at the counter, an indoor-outdoor flow that feels like a backyard. A 13-minute walk from Seongsu Station, pet-friendly.
