national museum would be a waste of time if u ask my opinion, in a way of saying there is a lot of place to visit in Dhaka, first of all take a map of Dhaka and start from one end, in my opinion the south, its mostly narrow street and historical places, the Ahsan Manzil, Lalbagh Fort, Boro Katara, Hosni Dalan, jus to name a few and yes lots of places to get street foods (typical Dhaka specials) there head on to the Dhaka University campus, u will find a few parks nearby, then go to Badruddaza Market, or Mall opposite Dhaka College a shopping heaven for any tourist, Theres also Bongo Bazar another favorite shopping spot for tourists given u have the bargaining skills. Theres a lake at Dhanmondi and many more shopping malls and food courts at the area, Bashundahra shopping Mall is one of the largest Malls in the country. National Parliament building is a place many tourist would like to visit, it even has a few gardens and parks around it, but one must take special permission to get a tour on the inside of the parliament building and the MP Hostel, these are just a few spots tht i can recal at the moment but as a person heads north in the city the get to see a more modern and upscale side of the city dwellers, Dhaka city itself is 400 years old, so theres always something in every corner u jus need to have the proper interest to get the feel of it, keeping an honest and friendly guide with you would help a great deal in choosing spots and bargaining deals
