Well i can intro you to one Chinese restaurant located in sunway area.
The location is quite hidden from the main road of Sunway.
It located at the sunway pyramid side of the road, went further down you will see a petrol station quite hidden next to the Sunway Inn near CIMB turn in to the petrol station there beside got 2 row of shop, its located at the first row once u enter there. There is one side with air cond another on with no air-cond.

Food that i would recomment will be
Hak Beh Pai Guat (Black Beer Pai Guat)
One of thier taufu is quite famous that you thought u eating steam egg insted of taufu.
The Fish dishes is absolute fantastic.

Give it a try and the price is very reasonable!!

i think is Sun Keng (Sun View or Sea View) i forgot >.<"
