It must be pretty tough living in Dhaka since people there have to come to Kolkata to taste shopping malls, multiplexes, nigh clubs, pubs etc. My condolence.
Going shanty town kolkata for mall, please don't flatter yourself. Dhaka has much better malls than Delhi (don't know about Mumbai) rest of india. Kolkata or even delhi is not in Dhaka's league. Delhi may have wider avenue and metro but still have historic look. Where as Dhaka has much more contemporary look and culture. It goes to show indians know jack about Dhaka yet running their tradition big mouth.
Once Dhaka has its mass transit and ongoing flyover/elevated highway projects completed, living and driving should be better. Mall, multiplexs are things people enjoyed for many years in Dhaka. For shopping those who can afford goes to Thailand, Malaysia, Dubai.
