I've been to Bella Napoli quite a few times and overall, the food is very good. If you're looking for fine dining though, this is probably not the place to go. It has a family-friendly, casual atmosphere. Dishes with FRESH mozzarella are very good (they make their own mozzarella). If you ask nicely and call a day or so in advance, you can even buy their mozzarella and take it home with you to use for your own dish. Grow your own tomatoes in the summer and slice the mozzarella onto tomato slices. Lightly salt and top with fresh basil leaves from the garden for an excellent summer appetizer for your family and friends.
The only thing I don't like about Bella Napoli is that certain tables are in cold spots. Be sure to bring a sweater just in case you end up at one of those tables.
