The surest way to get to know a city--any city--in the here-and-now is to sit in a coffee shop and watch people go about their daily life, not visit museums and monuments. (Those serve a different purpose, and are meant to express the essence of a culture at its pinnacle.)
My best people-watching experiences so far have been in Tokyo and Moscow. The Baltic trip has been the epitome of tourism--organized and guided sightseeing, by and large--so I have had very few opportunities to engage in documentary street photography.
Yet there have been some exceptions too, and this street musician from Stockholm's medieval town is one of my favorites.
