Why Visit: A center of culture and a new restaurant destination for Bostonians. Assembly Square offers everything in the way of shopping, and there are too many delicious places to eat than I could name. Live music and theatre all over the place, and a great place to spend a day.
Why Live There: More bang for your buck than in Cambridge with a similar location and many of the same amenities. A little quieter with a little more space than you would otherwise get in the city, and still a cultural hotspot.
