New World Park food centre in Swatow Lane, off Burmah Road, Penang, offers a huge selection of Penang hawker food, all in one place. But my fave there are the Cantonese noodle stall which offers Sar Hor Fun (stir-fried hor fun & bee-hoon rice noodles with char-siu, shrimps & egg) and Yee Fu Mee (another stir-fried option using an aromatic, toasted form of noodles which was absolutely delicious!).
There was also a Penang-style curry noodles stall near this one which serves its noodles with cockles, cubes of pig's blood, tofu puffs & cuttlefish.
Didn't try the other food options there, but the Penang rojak & ice-kachang looked popular, so's yam cake & otak-otak.
