Manly Beach is an outstanding day trip if must make sure a visit from the CBD getting a ferryboat.
Another place to check out is China town just to the south of the CBD. Almost every any beach in Sydney it is surrounded by some great pubs and eateries. https://Medium.com/@healthsupplement00/the-best-cbd-health-products-to-boost-your-wellbeing-3e8d4d254a7b
