I lived just outside the city of New Haven a few years ago and enjoyed every opportunity I had to go into this very small city. It's an old seaside town with plenty to do and see.
One real positive about New Haven is the crime rates, or lack of crime. New Haven is known as a very safe city, so you should feel comfortable raising your family in New Haven.
Museums in New Haven like the Peabody Natural History Museum and the available Yale University art and history exhibits make for great afternoon dates or family outings. Restaurants in New Haven are plentiful, and all delicious! Pizza lovers should try "New Haven style" pizza from Frank Pepe's Pizzeria Napoletana; it's a real treat.
Though New Haven has lost some of its reputation over the years, it is picking up again, becoming a great place for singles and young families to live, with a happening social scene and quite a lot of culture and attractions.
