Only open for certain days close to the weekend, this is a place where you need to be prepare for a long wait.
I came on Saturday morning before lunch time and there were already a super long queue. I took more than 40 minutes just for the queueing.
I have to agree with most people that this is one of the best kway chap in Singapore. The chap was flavourful and all the intestines got a strong βlorβ taste. $5 for one person
