Needless to say, Sydney also has a Chinatown, a neighbourhood filled with colour and restaurants. We recommend walking through it, especially Dixon, Hay and Sussex Streets. You might feel slightly assaulted by the Chinese waiters trying to convince you to eat in their restaurants! If you're interested in trying one, we recommend The New Thai Yuen, on St George Bank. It's not easy to understand them but we came to the conclusion that the Shizuen chicken is their specialty, and truth be told, it was pretty good! 15-20 AU$ per dish.
You can get there on food, 20 minutes walk from the hotel.
