There are 4 famous stalls(47, 49, 57, 328) or more in the same row. I have compared 49 and 328 on the same day. If I am not mistaken, 328 is the older laksa stall and 49 is quite new. However, both stalls is supported by their big group of laksa fan.
49 Katong Laksa Stall
A bowl of Katong Laksa is always complimented with otak and a glass of barley drink
After that, I moved to the opposite shop, 328.
Still photos everywhere
If you were to ask which stall is better, I will go for 328. There might not be a big difference in the katong laksa, but I feel that 328's otak tastes better than 49's otak.
Little opinion, do not compare it with penang laksa or any other laksa, take it as a new dish. I am sure you will like it too. To me, it definitely worth travelling down for a bowl, or two.
