wedding dress

In two weeks I am headed to Boston. I have only ever had a brief stop over in Boston, I am very excited to spend some quality time there. I will be seeing most of the big historical sites with my class but I have several afternoons and evenings to myself. I have been doing some research to find some good restaurants and sites to see but I am overwhelmed by the amount of information available. The only extra-curricular site I know I want to visit is Harvard. Any recommendations for restaurants and sites to visit?
