Enjoy fish? Then you're going to the right place. Bangladesh is known as a fish lovers paradise with most the country living of fresh water river fish and rice. Most popular is the 'national fish' Hilsa, it's very tasty but somewhat difficult to eat on account of its numerous fine bones.
Bangladesh has a tropical climate with a generally mild winter running from October to March and a hot humid summer from March to June. As a country Bangladesh has never been frozen at ground level with the lowest recorded temperature being 4.5°C in 2011.
Take the tour deals seriously: Pretty much anywhere you go (of the major tourist destinations) there are sure to be tour pamphlets sitting around with great deals. From boat rides to day trips, there are great tours around that will get you where you need to go.
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.
Be aware though that Bangladesh is widely recognised as one of the countries most vulnerable to climate change and in 1998 has been subjected to he worst flooding in modern world history.
