Nightlife in Bangladesh is nearly non-existent. Being a Muslim country, alcohol is frowned upon and found mostly in the international clubs and pricier restaurants in Dhaka and in some restaurants in tourist centers like Cox's Bazar. In Teknaf and on Saint Martins Island you may stumble upon the occasional beer smuggled in from Myanmar. Some of the nicest hotels in the cities have fully equipped bars with exaggerated prices to match. However, lack of commercial availability of liquor should not always be confused with cultural aversion to alcohol in mainstream society. You'll likely find that Bengali Christians and many urbanized, upper-class Muslims privately have a more liberal, Westernized attitude toward social consumption of alcohol. However most 5 Star Hotels like Radisson, Sheraton. Shonargoan, Regency etc and few clubs in Gulshan are arranging DJ / Dance parties on frequent basis. Foreigners may bump into one of those parties if they are lucky. Usual entrance fees of such parties aare around BDT 2000/- USD 30. Young people of upper class and higher uper class of the society are the main portion of the formed crowd. How ever in some places, western clothed hired companions are available. Foreigners looking for a clean vacation should stay away from them using common sense. Liquires does not flow freely in these parties most of the time.
Coffee is -- like the rest of the world, a perennial middle-class 'Adda' gossip accompaniment in this city. A favourite haunt for coffee-lovers those with a 'Starbucks' bent is 'Coffeeworld' (http://www.coffeeworld.co...), Dhaka branch addresses about seven so far given here, Dhaka Coffeeworld joints (http://www.etceterabd.com...). Most coffee aficionados here rate their 'Caramel Macchiato' better than the plain Starbucks variety and cheaper to boot about US$2! In most places instant coffee will be the best you can find
Tea is everywhere. Ask for red tea if you do not want milk.
Fruit juices are plentiful, varied and delicious, though be wary of watered down or icy drinks and dirty blenders. Raw sugarcane juice is widely available during the hot season, and usually a safe, sanitary bet. Other safe bets are coconuts, popular in the southeast tourists spots like Cox's Bazar and Saint Martins Island.
