If you’re longing for Southern Italian food, this is your spot.  With indoor seating in an airy white space in the winter and outdoor seating in the square in the summer, Acqua Pazza offers seafood, buffalo milk mozzarella, pasta and a wide range of pizza.  The vegetables are quite special especially the grilled vegetables which are the lightest and tastiest we’ve ever eaten.   Our only quibble is that the sometimes the waiters have a bit of an attitude.  Favorites: Branzino Acqua Pazza (whole striped bass prepared in white wine, olive oil and tomatoes); grilled vegetables; mixed salad; spaghetti with clams.
