240B is the "B" entrance to 240 Elm Street - also known as The Social Security Building on the corner of Elm and Chester in the heart of Davis Square. On the actual corner is Duncan Donuts, but that is all part of the same building. Next to the Duncan Donuts on Elm Street are three entrances. The first one, 240, goes into the Social Security office. You don't want that! The next one, 240B, goes into a foyer with mail boxes. That's the one. We are right at the bottom of the stairs. You can't miss us. 240A goes upstairs. You don't want that either.
