Their food
There is a massive amount of Polish food here, in fact it is difficult to get anything else. Street food, beer food and a couple of French or Itilian places, being the exception.
way they live
Emm, Yeah, ok.
how they relate to visitors
Well just do not expect everyone to speak English. I remember meeting some Brits who thought the bartendress was impolite because she did not speak English, she was my friend. I am sure you will be fine.
the architecture
Simply wonderful, I recommend looking at a map of the centre of Krakow now and you will see the medieval layout, castle on top of hill, the green going around the market square used to be a mote. The architecture is simply divine, you will love it.
their history
Krakow is covered in History.
Shall I draw a Picture
Yes that would be wonderful and then you could post it on here, but I think you were being a smart arse and nobody likes a smart arse.
