It took me years to uncover this gem, and it was by chance.
The thing about Chinatown Complex is, there are too many good food stalls crowded together in the hawker centre. In the rather obscure Green Zone alone, there are five zhi char or Cantonese dai chow stalls - all are good and have their own loyal following. (Chinatown Complex is divided into four zones - Green, Yellow, Red and Blue.)
One of my current favourites is Lin Da Qiang 林大强.
