People from all over the world come to the small city across the Charles River from Boston to work, study, create, and among other things, enjoy the hundreds of restaurants which offer cuisines from Ethiopian to Mexican, priced in ranges for high dollar spenders, families on an outing, and grad students on tight budgets. High end Henrietta’s Table and student friendly Bartley’s Burger Cottage make all the guidebooks, but there are other great choices, too.
