Hi Helen!
Thank you for bringing your question to the Disney Parks Moms Panel!
Tutto Italia Ristorante and Via Napoli are both wonderful choices. Tutto Italia does offer a Kids' Menu with spaghetti, chicken tenders, pizza and mozzarella sticks, so your kids may be fine with it. But, Via Napoli has amazing pizza and their other entrees are delicious, too. I have had the lasagna and chicken salad before and they were both great!
If my kids were to choose, they would choose Via Napoli. In fact, we go there almost every trip. The pizza really is delicious. But, honestly, they both have great food and would be excellent choices.
You can look at their menus online to see if that will help with your decision. You can find the
Tutto Italia Ristorante menu here, and the
Via Napoli menu here.
I hope this helps! Please let me know if you have any other questions.
