As far as food goes, I have not been anywhere that serves as a good a bowl of laksa as 328 Katong Laksa. Like the fact that they cut the noodles, so it can be eaten with a spoon (I am not so good with chopsticks). The soup is AMAZING. Best laksa soup there is in my opinion.
Unfortunately, it is usually very crowded and noisy. The service is not very good, especially because I don't speak Chinese. The food takes a really long time to come (in fact I've only had this kind of waiting period in really fancy restaurants where everything else is good except for the food, which I usually do not like).
So go there for the food but not for much else.
