Keep in mind, I grew up in the northeast (in part in Maine).
I would never eat in one of those places again, and I've tried the three main ones, Boston Lobster Feast, Angel's and Lobster whatever (can't even remember the name; the one on I Drive)!
They are dirty, and the lobsters are overcooked culls. The clams at Boston Lobster Feast (the one near the Florida Mall) were actually filthy, as in black mud on my plate. Inedible.
Kids are running wild, and people are sometimes pretty disgusting. One seafood bin (the mussels) had the service spoon completely submerged, so people were reaching in with their bare hands... you get the picture.
Nope. Not us. Never again.
