In Vienna there used to be a hustler bar called 'Boyzone', where I could see many boys from Slovakia, Czech and Hungary, 2001, 2002. When I visited Vienna 2 years ago, the venue had already disappeared, sadly.
I researched to find any new hustler bars in Vienna, but no luck. In Berlin, in those bars still exist, but there were so many boys from further south-eastern Europe, who are far from Belami type of boys.
