The unassuming outlook of Ai Tongue could easily be overlooked by pedestrians, but this homestyle Hakka eatery has its charm. It is a family-run restaurant with no more than 30 seats and a casual setting. The restaurant serves Hakka home dishes, together with a wide selection of double-boiled soups. Stir-fried vegetables with crispy pork lard is a popular vegetable option, with crispy lardons to accompany tender greens. Rice in a claypot is particularly popular here. Cured meat toppings are reliable, but the belly of carp fish with duo chillies is the real star.
