I called earlier today and learnt that their tau sar piahs do not contain pork/lard, butter, eggs. Except if you choose their cheese flavoured tau sar piahs.
Not a veg shop, their signature i think is some chicken puff thing. But their TSPs are made vegan. Not suitable for those that mind cross contamination.
Their crust is crispy and flakey. Fillings very generous too! And they are thicker than House of Tau Sar Piahs.
Very near to House of Tau sar pia and the famous but non-veg Loong Fatt.
