If you have time, Salem is a 45 minute drive from North Station or a 30 minutes train ride from North Station (on the Newbury/Rockport commuter rail line) and is an amazing place to check out around Halloween. It is famous for its 1692 witch trials, during which several locals were executed for allegedly practicing witchcraft.
If you want true New England food, this is your place. The fried oyster sandwiches, lobster roe noodles, burger with fried oyster (Matt believes best in Boston), and the banofee pie are our personal favorites, but you cannot go wrong with anything on the menu.
