Ngee Ann city is in the heart of Orchard Road and is definitely different from Vivo city. You can find the One and only Takashimaya in this area- a Japanese Department store.Head to ion Orchard basement where you can get affordable n expensive local food. Try walking over to Tangs department store basement to try more affordable Singapore local food but do not expect big portions. It is always crowded over the weekends . There is also a book shop Kinokuniya on level 4 of Ngee Ann City. Level 5 of Ngee Ann City has a variety of food from Chinese to Thai Indonesian. Hope this information helps
