I have wanted to try this when they first started in Toa Payoh. Before I find the chance to go, I just realised they have moved to Chinatown; which is much convenient now to visit (since it is near my workplace).
The auntie was very friendly and all her dessert worth trying and take photo.
The monster treasure comes with chendol worm, red bean, taro pearl and lots of grass jelly with attap seed at the bottom.
