Sonsie has lasted because it's consistently good and the service is up to par. The menu changes a few times a year but you can always ask about your favorites. They might still be able to make them for you. Have dessert only in the tables up at the front or settle in for a meal in the dimly lit restaurant area. When they open up the French doors in nice weather there is no better people watching on Newbury. I don't live in Boston anymore but you can be sure that I go back to Sonsie whenever I'm back in Beantown.
