One of the best places in the world for drinking coffee is Vietnam. Especially the capital Hanoi is full of high quality coffee shops. The usual taste of vietnamese coffe is strong and the core taste is nutty. Most of the beans are dark roasted and not bitter. Ask for the coffee fin, which means filter coffee. Also highly recommende is the weasel coffee, which is related to the same named animal that gives the beans a very unique taste by detracting the bitter parts of the beans through digestion.
