Hello,
Sorry to hear your opinion. The restaurant we use with the dancers is a top notch place in Sofia. Very authentic with traditional Bulgarian dances, meals and drinks. The hits you mention are probably in the pauses from the program as somebody requested that from the foreign groups there.
Sofia has got charm at night. The guide is explaining about the sight which the bus passes and the history behind them.
Next time while in Bulgaria, give us a call and we shall personally assist you on a similar tour to make it more special for you.
Best regards,
Hristo
