The busiest place in Sofia by night recently. The small park takes its name from the eponymous restaurant of the communist era, unsurprisingly (the park, not the restaurant) has been used as a place for civil protests against regime for many years. Crystal attracts a colourful mixture of young people with beers, bikes and skateboards, hipsters, dogs and common drunkards. Take a look at the astonishing monument of Bulgarian politician Stefan Stambolov, whose face is slashed into two – direct allusion to his assassination in 1895 just meters away from the park.
