Despite being a residential estate, City One is able to satisfy all shopping needs of residents. There are two shopping centres (Fortune City One and Fortune City One Plus, formerly known as City One Plaza and Ngan Shing Commercial Centre respectively). Local businesses including home appliance stores, variety shops, book stores, jewellers, beauty salons, optical centres, boutiques, bottle shops and confectioneries are main tenants of the two arcades. There are also larger business chains within. The ParknShop Superstore offers daily groceries and necessities. Pharmacies Mannings and Watsons, provide shoppers with varieties of healthcare and personal products. Convenience stores Circle K and 7-Eleven support 24/7 services. The City One Shatin Post Office of the Hongkong Post provides postal and bill paying services in the heart of the estate. Branches of HSBC, Hang Seng Bank, Bank of China and ATMs of other banking institutions are conveniently scattered within the two shopping centres.
