The neighborhood around Arlington Center would include neighborhoods that could also be designation as Jason Heights, or East Arlington, or even Morningside, perhaps. But when people refer to Arlington Center, I believe they are primarily referring to the commercial district near the intersection of Mass Ave and Pleasant Street, the spot where the Minuteman Bike Path crosses Mass Ave. There are many shops, restaurants, and events in this location. Arlington Center is also the home to Town Hall, the Robbins Library and the Farmers Market. It is in many ways the center and heart of Arlington.
