Poland is a good place for holidays but here isnt 30'C everyday even in the summer time :D
My country isnt as much developed as Germany or England, anyway many tourists enjoy spending time here :p if you want to visit Poland one day, i can recommend you, first of all a city called Kraków(you can google it) and then Wrocław.. in my opinion, these two are the best here.. for sure you are welcome in my city - Gdańsk :)
and food? hmm sure :) i see you don't know much about my country because people who know Poland well, they appreciate our traditional food :)
