bro, I realised that you didnt include the koay teow thing of "7th street market" (direct translation from hokkien, somehow can't remember the real street name). That's my favourite koay teow thing. Dhoby Ghaut's koay teow thing also aint that bad but somehow still lose to the one at 7th street market. Try it out! Not hard to find the stall cos it's probably the biggest and busiest stall at the market. All their staff will be wearing yellow uniform if im not mistaken.
