Hire local transport for the day: One great way to get around is to hire a tuk tuk or a moto-driver for the whole day to take you everywhere you want to go for a very nominal price. Your driver can also work as a de facto tour guide, getting you around to the spots you may not have thought of and that you would regret not seeing.
Also, many of these countries have free English-written dining guides. Check them out.
This scotch does not taste like scotch: Drinks are a quarter of the price than what you'd find in Europe or in the U.S., the reason being that many of the typical name brands are regionally produced and use local ingredients, so don't be shocked when your beloved Grey Goose on ice tastes a little different from what you are used to. Use the opportunity to try some very interesting locally produced spirits.
Out with its cities Bangladesh is a country of vast natural beauty. To the far south east lies Cox Bazar, the longest unbroken sea beach in the world, boasting pristine sandy beaches, coconut palms and tropical climates. On the opposite coast bordering India's West Bengal lies the Sundarbans ('beautiful forests') which is the largest single mangrove forest in the world.
If seafood isn't your thing then mixed vegetable curries are plentiful throughout Bangladesh as are a range of biryani's (anything from egg to mutton and beef).
