Not Chinatown, but a buddy introduced me to this great Indonesian place recently: https://maps.app.goo.gl/5dSZUvuc1MXWSnc3A
Another vote for Malay Chinese laksa as well - I first went there 20+ years ago when it was underground on Castlereagh Street. Always consistently good.
Mensho is now my favourite ramen place, reminds me of a place I went to in Osaka - expensive but really good: https://maps.app.goo.gl/ussATST5JKbBjojt7
