I was going to meet someone in Glorietta earlier and I thought of passing by Rustan's Supermarket to kill time and try to search for A's chocolate. They didn't have them also, but what I did find are these:
There are 3 variants on sale:
dark chocolate filled with a coffee-flavored light mousse
milk chocolate filled with dried fruits
white chocolate filled with coffee mousse and roasted hazelnuts
It still doesn't beat A's chocolate dollar based on weight and price, but this is definitely a good treat!
