Durgapur is quite a decent city, I will post some pics of Durgapur later. Durgapur-Asansol industrial belt still has some good industries. I think Tata should have built the Nano plant in Durgapur instead of Singur. Shiliguri is a major trading hub of north Bengal.
I also think compairing Dhaka with Kolkata is a bit unfair. Dhaka still is a half-village trying to become a city, I agree that they have managed to get one or two multiplexes and shopping malls, but so does a small town like Burdwan in West Bengal, and both Dhaka and Burdwan largely depend on thousands of cycle rickshaws for public transport.
I think we should compare Dhaka with Burdwan, they differ only in size, nothing else!!
Bangal...!
