I hope the place still functions as it was a few months back that last I visited. http://bit.ly/nO36cb
But I will be more than happy to take you there :)

For the Vietnamese coffee you need the drip thing (http://goo.gl/HsNqM), and Vietnamese coffee freshly ground to #3 grain and condensed milk - Billa has Dutch lady :)

I will give you a new drip thing as there aren't many in BG and so it happens I have a few that I bought in Vietnam
