For those who love to travel to Vietnam in their own kitchen...
If you want things fast, make this iced coffee using a cup of espresso.

Vietnamese Iced Coffee ingredients
-3 tablespoons dark roast coffee
-3 tablespoons sweetened condensed milk
-a few ice cubes

Preparation
1.Put the sweetened condensed milk in a cup and add ice.
2.Put the dark roast coffee in a Vietnamese coffee press. You don't
need to go all the way to Vietnam to get these stainless steel looking
Vietnamese coffee presses. They do sell copy-cat single cup coffee
makers in glass-plastic in your decent household shop. (In Malaysia
these single cup coffee makers can be found e.g. in the Isetan malls)
3.Add water that just comes off the boil (for half a cup if you don't
want to monitor when your cup will overflow due to the extra ice in
your cup.) If you have a real Vietnamese coffee maker, screw to adjust
the lid over the coffee until you see bubbles appearing through the
water. At this point your coffee starts drips very, very slow in your
cup, which for me is still the charm of Vietnamese coffee!
4.When your cup is filled with dripped coffee, give it a stir and drink
your Vietnamese iced coffee!

You can also make Vietnamese iced coffee with a cup of espresso:

Put the sweetened condensed milk in a cup, add ice and poor your cup of
espresso over it!
