The exterior of the incarnation of 328 Katong Laksa that I visited at 51 East Coast Road, near Joo Chiat Road, made me think of some fast food chain style restaurant!
Obviously being involved with a Gordon Ramsay challenge has paid off for the owners, as there seem to be several outlets of the 328 Katong Laksa brand. I hadn't realised this at the time, but it would seem there is an outlet at Queensway Shopping Centre, another at 51 East Coast Road on the corner of Ceylon Road, and another at 216 East Coast Road. I think I read somewhere that there is a 4th outlet as well but I'm not sure of the address. The one I visited seemed quite new and the dominant colours were orange and white - an interesting combination.
It seems also that the price is a little higher than expected, probably again based on the popularity of the brand after its publicity. I can't remember exactly how much I paid, but it was a little on the steep side. Still, the price wasn't unreasonable compared to what I'd pay back home.
Service was efficient, but not really very friendly or anything. The laksa was tasty, and the seafood taste was slightly stronger than I was used to. The taste of the cockles was fairly strong, and in terms of this I preferred Sungei Road Laksa. Nevertheless, 328 Katong Laksa had more ingredients, so it was good that way.
They certainly put out a nice, tasty laksa. I don't have enough experience to be able to make bold claims like "Singapore's best laksa". I don't think it was the best, but it was certainly very good. Thanks and best good luck for the future!
