They are only at the Sri Petaling's Pasar Malam on Tuesday and opens at 5 pm. On other days they are at the front of a 7-11 shop in Damai Perdana, Cheras.
The mobile van's stall is parked opposite of The Store hypermarket.
They offers about 40 types of the best, clean and freshest ingredients and some are home made, too!
There are 5 types of home made sauces (very, very good) which are a real delight to go with the cooked or deep fried food.
My personal favorite are the sang cheong (pig's uterus), pig's kidney, ngap keok pau, roast pork, ham, fishpaste beancurd sheets, fishpaste pig's skin, Tofu pok filled with finely chopped cucumber and the cutely wrapped kangkong (water convolvulus).
