The Pav Bhaji's are all pretty much the same. I spoke to a mate who is from Calcutta and says Pav Bhaji is pretty ubiquitous all over India. He says bread-rolls are considered to be quite posh in a country that eats flat-breads or rice - which I found quite funny ;D Pav Bhaji is always made with vegetables, lots of butter, and the Pav Bhaji spice mix (which i've seen in the UK). If you look at all three of the pav bhaji videos above, they are all pretty much the same.
