I found a Central Asian cafe in a small lane in Nha Trang. I got Okroshka - a cold soup with kefir (a fermented milk drink) or kvas (a beer like, but non-alcoholic drink prepared by fermenting rye bread), cucumber, spring onion and bits of meat. There was a man from Tajikistan, we could exchange a few words in Farsi - Tajik and Urdu have several common words. This lane has backpacker places, and the guests seemed to be independent travellers from China. The flavours and sounds - a mix of China, Russia and Central Asia reminds me of the silk route.
