A "town" in Massachusetts which is either a component or a suburb of Metro Boston. It adjoins Watertown and is basically one big affluent subdivision with seven Bread and Circuses (and the glorious Marty's Liquors), but it's an old subdivision and not an unattractive one. It's a bit like the Haverford of the North if you know the Main Line at all. If you don't, don't worry about it; you're not missing a whole hell of a lot.
The Fig Newton is named for Newton, and I am not making that up. The North American Biscuit Company, creator of the Fig Newton, used to have its factory in Central Square, Cambridge; the factory has since been converted into pleasant apartments (the Kennedy Biscuit Lofts) with very thick walls and high ceilings.
