It is not open yet (I drive by at least once a week to check on progress during my lunch break), will let you know. Looks like it is getting close. I can't wait!
As for restaurants in Naples there is The Loving Hut which is 100% vegan (love this place, there were 2 of them in AZ), Noodle Saigon which is a family owned Vietnamese restaurant-not veg*n but they do have veggie dishes and some other assorted places that you can get veggie food.
If you want to make it a day trip what kind of things do you like to do?
