Last year, I went to the Baltics. In Lithuania, I met a local for a tour of the real market where the real folks shop. It was indeed quite “real” and there were very few tourists.
There were berries and spandex for sale.
Also dumplings and pickles.
It was the sort of place I would shop if I lived in Vilnius. I even got yelled at by the rotisserie chicken man for taking video of his chickens. Sorry, not photos here.
