Great news! Discovered a few more new vegetarian stalls at the newly reopened renovated Chinatown Complex Hawker Centre. And one of it is Lao Di Fang Vegetarian at economical price.
However, for their famous Spicy noodles, I would still prefer the version at their restaurant at #01-38, Apollo centre.
The stall is located at #02-158. From Escalator facing the Buddha Tooth Relic Temple, keep to your left and go straight once you are up the escalator and turn left after the corner hand-made soy-drink stall. You will find it on 1st corner stall on your right.
