Shorter and longer = better
2001racer, as above, if it's Boston seafood you seek, you will not find a better Legal's than the one landside in "C" Terminal (United etc.). If it's a view you seek, you will not do better than to take the Hyatt shuttle over to the (airport) Hyatt Harborside. The views of Boston harbor and Boston proper are world class. And then there is a very pleasant, fairly new, promenade out along the water for a good walk and sea air. All without the time and hassle of to-ing and fro-ing from downtown. It doesn't take very long to get downtown, but all that time (and $40) could be spent on a longer dinner.
