If you have to try only one Thai style wanton noodles in the Katong/Mountbatten area, let it be Foon's.
Oodles of flavour imparted from the lard oil, fish sauce, chilli powder and crushed peanut coated springy egg noodles. The fatty slices of char siew were slick with marinade and the dumplings, generously plump with pork and prawn. Addictively crispy bits of lard are buried under the noodles as well, so good you can't help but throw any health concerns to the wind and devour them all.
Better than any new fangled onsen egg, pork collar toting modern variant I dare say.
