Birdy's New york pastry - I am not sharing this

This is picture of one of my favourite pastries. It is called 'New York pastry' - I don't know why.

It has everything I like about pastries:
  • Chocolate based
  • Sponge (as against mousse or cream based)
  • Juicy
  • On the sweeter side
  • Not too expensive - Rs 50 (1.1 USD)

I have tried pastries from various places over the years but this remains one of my favourites...and I don't like sharing it
