Phở Hiệu is a small pho shop on a pedestrian street near Hoàn Kiếm Lake in Hanoi, serving chicken pho as its main dish. The broth is clear and light, and diners add garlic and chopped chili to make it spicy. The shop has six to eight tables, with both indoor and outdoor seating. The menu is close to a single item, so choosing other food is difficult.
