Ask questions, meet dancers, and be part of the conversation.
I do have experience with the Sofia tango community as I happen to be from Bulgaria originally. Is there anything specific you'd like to know?
...and will they dance with a non-Bulgarian-speaking slightly eccentric English lady?
But of course. As usual, the best strategy for you will be to invite with the appropriate British aplomb every eccentric Bulgarian gentleman hanging aroundIt is a pretty laid-back community you know, so sometimes they need a bit of push...
