Yup - first ate at Legal in '69: Inman Square was a dumpy mess,
with Legal not adding much to the atmosphere of the area; the
place was cash-only and, by then-current standards, not too cheap;
the seafood was good - perhaps not better than at the clam
shacks and lobster barns up the coast, but certainly among the best
that most of us non-New Englanders had ever encountered. And the
place was packed even on weekday nights.

But in time the Berkowitzes got a bit big for their britches, with the
result that you see - not cheap, and the seafood is decent, perhaps
among the best that non-New Englanders have ever encountered.
Even the one at Logan C - if I have been hit by a delay, I'll duck in
there and get steamed mussels and a beer and be perfectly happy.

If you go with a simple preparation, you're likely to do okay; but
as soon as they add a sauce, all bets are off.
