Sunday, 11pm onwards to 2am in the morning of Monday.
I'm ok with walking 15 minutes to Chinatown, but is it safe?
Also I assume the subway doesn't run during that time right? So the only other choice is uber/taxi?
Sunday night is a dead night.
There's Mamak that's open very late if you want exceptional Malaysian food. That's on the edge of Chinatown. Agree Golden Century is highly priced and service terrible but food is reasonable.
Hubert's is not open on Sunday night.
Quite frankly to get really good food, I'd probably Uber/Taxi to Surry Hills or Potts Point or Darlinghurst. Even Newtown.
Sunday night in the city is a ghost town.
