Had also booked for a river dinner cruise and we were delivered to the Folklore evening instead! A bit of a surprise but in the event it turned out very well. The food was real Czech as was the beer and wine which was free all night! The entertainment was good, a whole evening of Czech songs and dancing. People were there from all over the world. A really good evening which we would recommend to anyone. Just be aware if this happens to you to remember to ask for a refund as this was 700kroner cheaper!!
