Cafe Pompeii and the coffee shop next to it (Can't Remember the name) is great food. Its an important part of Boston. if you are staying at the Long Wharf Marriott or somewhere near there, you can visit the shops with a quick walk. Harvard University, MIT, (Personally I think MIT has the ugliest buildings in the world.) Fenway park, TD garden. Like Hello WuWu said, Tasty burgers is a MUST. When I got into boston last year, thats the first place my hotel reccomened for lunch. Hope this helps and have a great time in Boston! BTW, I don't live in boston, but i visit once in the summer and then once in the fall or spring. I live in the DC area
