Legal Harborside is the massive flagship restaurant of Legal Sea Foods, a Boston seafood institution that now stretches its grilled tentacles up and down the East Coast. This location includes three different restaurant concepts in one: a casual restaurant on the first floor with a big bar, a white-tablecloth dining room on the second, and a roof deck with drinks and small bites. The menu is a little more interesting that what you get at most Legal’s locations, and the roof deck provides some of the best harbor views in the city.
