I have tried these several times and well, I think it does taste a bit like the real thing.
At first I was quite sceptical about it especially seeing the white powder and black soya sauce..
But the result, though not as perfect as the real Har Mee or Penang Prawn Mee is reasonably good. You can add prawns and chicken bits if you like for a more authentic taste.
For me.. My instant noodles is for lazy days.. So I just like it plain.
