Now operated by the daughter, I have been chomping down their "hum jin peng" (they sell this and only this) since the father's time. Believe it or not, one piece used to cost only 10 cents back then but prices have risen slightly to 6 for $1 (or 3 for 70 cents). They offer two types - salty and sweet. I personally find it hard to discern them by sight but I think the sweet one has got more sesame seeds and subtle dark patches on it (this is due to the red bean paste inside).
What gives this stall an extra special touch is the long wooden chopsticks provided for customers to help with the frying. The lady owner is usually busy cutting and rolling out the dough before dropping them into the deep pan of hot oil. So it falls on the customer, especially during peak periods, to give a hand with the frying of their own order, flipping the "hum jin peng" over as they puff up to get a nice even golden-brown colour. This clever teamwork helps the queue to move along faster as well. A win-win situation.
