I would also like to know. There used to be a Penang food centre
at Katong East Coast Road. Many called that particular location a
jinxed one, and sure enough it closed shop later on. I think the
only place selling all Penang hawker foods is at Copthorne King's
hotel, Havelock Rd. Even then, I'm not sure whether it is still
going on, as I haven't been there for many years. I think, even in
Penang, there can be many versions of Penang Laksa. Some even have
Sardines added to it. I've seen some foodcourts selling Penang
Laksa and Char Keow Tway, but can't recall any right now.
