1428 SPECIALTY COFFEE is on the second floor of an alley next to Hoan Kiem Lake in Hanoi, serving specialty coffee. Its signature drinks are egg coffee topped with cinnamon powder and cold brew made with lemon. A passage between buildings leads to stairs up to a large second-floor space with views of a park and the lake. The entrance is a small alley that is hard to find because it differs from the location shown on maps.
