Once again thanks to all of you for the suggestions.
I actually need the soon kueh tomorrow however when I wend to People's Park Complex food ventre for the famous yong-tau-fu this afternoon I was pleasantly surprised to bump into this.
And there was a notice that says they don't open on Sundays so its really my lucky day if not I'd have gone to their Serangoon shop tomorrow and come back emty handed and my overseas friends would have miss the treat
Too bad for me they ran out of kuchai kueh but what the hack bought 20 soon kuehs and 10 png kuehs only $27
Was advised to keep in fridge after cool and steam for just 5 minutes.
