I came across few stall call Sister, and they all serve fantastic food. I think when few "sisters" join together doing something special, result will be tremendous.
There is one corner house at Batu 9 Balakong serve very good Pan Mian. Few sisters running the stall and normally it is full of people.
I do not really prefer the place because it is hot, very hot during lunch time and you got to wait. After meal, I always look like I have been to sauna. But I am amazed when I saw many girls sat there waiting patiently.
Good things got to be waited.
I once bought my wife there and until now, she still crave for it.
