The Kopitiam "林爹.饮茶 LimTeh.YumCha Cafe" opens everyday as early as 6:30am - 4pm, several night stalls will then offer evening meals until before 10pm.
The only thing which got my attention is the Beef hor fun which is not bad but is not in the menu. You have to ask the chef to cook for you..Hahaha.
