Chequers on Goulburn St
Babylon @2/F Market City
Both shops have Chinese RnT and Korean B2B
Masstige 8 on Harris Street (Korean B2B)
Impressions @485 Elizabeth Street Surry Hills (Caucasian and mix B2B)
You can also try the Chicago on Pitt St opposite the World Sq, but not sure about their standard.
Have fun
Cheers
