Yang Cheng has been in Tainan for sixty years, located in an alley off Zhongzheng Road, specializing in Cantonese cuisine. Famous for sweet and sour pork ribs, mapo tofu, taro duck, stir-fried beef with scallions, shrimp with cashews, and signature roast chicken, it's so delicious you'll never forget it. Especially the roast chicken, prepared with a special technique that leaves the meat slightly red at the bone, don't be afraid, this is authentic roast chicken. It's cooked using a semi-poaching, semi-braising method to bring out the chicken's natural sweetness. Even the breast meat of our roast chicken is tender and not greasy, welcoming more people to taste the deliciousness of this old establishment. Address: 臺南市中西區中正路199巷5號 Hours: 00:00–23:59 Tainan
