Yeah we too find it slightly confusing when we write about this place. Pitt Street Koay Teow Th'ng at Carnarvon Street. Well, they moved from Pitt Street and the name remained. And so are the qualities you can expect from this well-known KTT stall.
Unlike many koay teow th'ng stalls that serves fish balls made of West Saury (西刀鱼) which are usually bouncy; the stall is famous for their fish ball made from eels (鳗鱼) that are extremely soft.
You can ask for a separate bowl of extra eel fish balls if you're a fan; though we find that we love their handmade pork slices to be more attractive. We are probably more used to fish balls that are bouncy.
Their broth on the other hand, is quite flavourful topped with extra chopped fried garlic and pork lards.
