I loved Vietnamese coffee last time. But not find it too sweet. My family actually bought the drip coffee equipment and coffee beans the last time we went to Vietnam, but it was disgusting when we tried making it ourselves =(.
Never tried it without condensed milk or egg yolk before though, definitely want to.
haha I have a similar experience when I try to make real malaysian kopi at home. Never can make as good as they serve it in Old Town for example.
