We ordered small size ($5) which has clams and unshelled prawns x3, medium size ($8) which has more carbohydrates, prawns, and clams, and the $15 portion which is a big bowl with crayfish and clams. We shared all the "liao" among ourselves, as the big bowl has lots of clams and 6 x halves of crayfish. Despite the slightly steeper price than normal, it was well worth it for the generous amount of ingredients and sweet sweet soup. We ordered all bee hoon so as not to let the alkaline taste of yellow noodles affect the soup.
The stall has a long queue but they cleared us quite fast.
Enjoyable food, they deserve the good reputation that we have heard.
