I bought 2 egg tarts from them (at Crystal Mall) last month. They were obviously days-old, not just day-old. I had to spit it out after the first bite and then I threw them both away.
I had bought egg tarts from numerous bakeries before. Sometimes I left them in the fridge for the next day and they still tasted okay. But those 2 from X福餅店 were so 'aged' that they tasted horrible on the day they were sold.
Will Never go back.
Not surprised in Crystal Mall, that place is so dirty everywhere! There's no way you can catch all the mice because after you cought the ones in your premise, others from next door will come to you, there's no end!
