What a view! The enormous rooftop bar of a 3-floor complex of the Legal Sea Foods chain looks out directly over Boston Harbor. It attracts waves of folks bar-hopping through the Seaport District, especially on warm summer nights. Retractable glass walls and ceiling allow the bar to be enclosed in cold months and fully exposed in summer. More than two dozen wines are available by the glass, along with a respectable sushi menu. If you need a bigger food menu, the second floor has a fancy restaurant and the first floor offers casual patio dining.
