My wife and I have lived in Duluth for almost 20 years, and have seen several restaurants come and go in that time. The Berarducci's Va Bene is our favorite place. The restaurant literally hangs out over the lakewalk, and the views in the evening are spectacular - especially when there is a full moon rising over Lake Superior. There is a small bar in the main room with a mostly young crowd. The decor has a modern European feel. There is a Gelato case with a huge assortment of flavors, and European foodstuffs like pasta and candy are for sale.
The food is always great. Most dishes are pasta based and include very fresh seafood as well as more traditional fare (meatballs, Italian sausage etc.). The salads are excellent (Nicoise with salmon, beef tenderloin tips on romaine are my favorites). Mary Kay Berarducci makes the best cakes in the world. Don't miss the Italian cream cake.
I just wish the place wasn't quite so popular, and that they had some parking available, but that's the price of success.
