They have multiple stalls. If you happen to be at Haig Rd, be sure to try the one in the hawker centre. It is cheaper at $2.50 for 5 freshly-made putu piring compared to $3 for 5 pre-made putu piring from the coffee shop.
Pardon the mess, there was no good way to deconstruct the kueh that started to stick to each other after steaming in the box for hours. Best eaten hot!
