Have you noticed how Mumbai will have a Madras Cafe and a Chennai will have a Bangalore Bakery and Kolkatta will have a Dilli Chaat.
I am sure I saw a Taj Mahal in Amsterdam and a Ganesha Pub as well!
Even within a city, eg. Adyar Anand Bhavan would probably have branches in Anna Nagar and T Nagar.
As an individual you wear your origin with pride( at leats you should)
I suppose that helps even when it comes to shops.
We try to recreate pockets of familiarity wherever we go. Nostalgia seems to be the common thread running across. And if it makes business sense all the better!
What do you think?
