We went to Wroclaw last month. We found that a main course in most places was about 10 euros, with a starter/desert 3 or 4 euros. It was possible to eat cheaper than this - there were some great canteen looking places where you helped yourself from a buffet which were really cheap. Beer was about 2 euros for a large glass. Wine was relatively expensive. We spent about 35 euros for the 3 of us to do an electric car tour round the city for 1.5 hours - DH had sprained his ankle A boat trip cost about 3 euros each. Krakow is lovely. I would definitely recommend a visit to the Salt Mines if you can squeeze it in. One of the most amazing places I have ever been.
