I bought a Vietnamese coffee maker when I was in there last year. If you go to any restaurant in Vietnam they make your coffee for you right at your table with one of these babies, its a French colonial influence. http://www.espresso-machines-and-cof...fee-maker.html

They are a lot better than the plastic ones that have been posted because they are metal and tough. They don't make the coffee taste like hot plastic, they don't require paper filters so there is less to carry, and they are a lot smaller because they are meant to actually BREW the coffee rather than just drip over it.

With the plastic ones I have used, this might not be true for all, the reservoir is always too big and once you pour the hot water in it goes straight through the filter very quickly and leaves you with watery coffee. Not so with this little beast. The reservoir is much smaller which forces you to refill it 2-3 times for a cup of coffee but it insulates the top of the mug while you are doing it so your coffee ends up much hotter, and darker than with other drippers. They come in a couple of sizes but the smallest one is best for touring. If you tour with a lot of people just get a couple of the small ones because its easier than one big one.

There are a lot of them on Amazon for about 3-5$ This one looks a lot like the one I have. I should have gotten more than one when I was in Vietnam because mine only cost about $0.25 or 5,000 dong! http://www.amazon.com/Newstar-Intern...f=pd_sbs_gro_1
