My husband and I are visiting Boston mid January for 3 days. We love great food and particularly enjoy a local experience. We want to visit some historic sites in addition to the JFK library. Neither or us enjoys shopping. Any recommendations on neighborhoods? Copley Plaza seems a bit too touristy (though close to some things we want to see). North End may be a bit rough (but maybe not...you tell me). South end? Back Bay? Appreciate all help. Also, restaurant recommendations? We don't want a tourist trap experience but DO want at least one fine dining and other lovely haunts. Merry Christmas!
