Tried the sang yoke bao when I got home; it did not disappoint! I enjoyed its light and fluffy texture. The egg and pork was filling as well.
This little "factory" cum shop in Tanjung Sepat makes and sell over 1000 bao a day, from an interview article in Sin Chew Jit Po, it also said that they have branches in KL, Melacca and JB (Setia Indah)!
