The O Bar is located right in Sydney’s Central Business District (CBD), up on 47th floor on Australia Square. This bar features 360 degree views of the Sydney Harbor and overall city. The drinks are pricey, to be expected, and the restaurant rotates at the top floor, giving you a full view of the city while lounging away sipping cocktails. This place is great for early evenings, as it did get crowded towards the later part of our visit. Not to be missed!
