This shop specialising in Huế-style bún bò makes its robust, savoury broth fresh every day. Pick from four toppings including the signature xí quách: the large L-shaped beef bone lends deep flavour and a wealth of textures – meat, cartilage and fatty edges. For a more varied bowl, try the thập cẩm, which comes with beef blood curd, pork loaf and tendon; the thinly sliced beef tongue is tender and delicate. Arrive early as beef bone availability is limited.
