very true.....just a decade ago a colleague of mine was posted to Chennai and he was from Delhi....surprise surprise!!! his wife was worried stiff about waht they would feed their child as she had heard that one eats only idli/dosa 24/7....and yes that milk wouldnt be as good .....ofcourse it's a different story that they have now bought a house in Chennai and dont have any intentyions of going back.
