A place such as Dwor Polski should by its reputation be one of the eating highlights when visiting Wroclaw. Sadly my experience there was that it was just an average eating house. Over a few years we've come to expect a very high standard of food when eating out in Poland. And that is in a variety of places from small cafes, pizza restaurants, chain "pubs" and "up-market" restaurants. This may have been an off night or trading on reputation. Don't know and probably won't find out when back in Wroclaw in a few weeks. Other places to try.
