Hello everyoneIm planning to move

Hello everyone
Im planning to move with my family to Italy. I want to open a small restaurant. I have two kids. One is three years and the other is 7 years. My questions are as follows and would appreciate of someone could answer:
Is it easy for my kids to learn in italian schools and are schools free for foreign residents?
Where is the best place to open a small restaurant?
Would appreciate any tips on the matter. Thank you
