Koffee Sniffer Seoul City Hall is a cafe in the Bukchang-dong alleys near City Hall Station that roasts its own beans and serves specialty coffee. Its drinks include the custard latte, the sniffer latte, and hand drip, with Brazilian beans described as nutty and Ethiopian Yirgacheffe as distinctly acidic. The cafe is crowded at lunchtime, and its seating is arranged for two people side by side, which suits a short stop. Seats are narrow and some benches have no backrest, so staying long is difficult.
