Hit it yesterday. The sheer variety was astounding. Wish I had had friends coming over because they had whole head-on red snapper that were large and very pretty.
Prices were a little higher then when I was last there on Christmas Eve (sweet shrimp and halibut), but fish IS expensive this time of year cause you have to be a bit crazy to go fishing in the Northern Hemisphere in February. And if it's flown in, well then it's expensive regardless.
I settled on some wild salmon and some sardines. The sardines were full stop the freshest I have ever had anywhere. They were glistening and opalescent like the fresh out of the water mackeral I sometimes catch myself. And they were sweet and delicate with not a hint of the fishiness (which I don't mind in sardines) that these delicate fish sometimes have.
It's worth the trip. It is a destination in it's own right. I'm not the first to say it (9Lives) but if you want fish in Boston, it's hard to beat New Deal.
