Courthouse Seafood is a block away from New Deal Fish Market, and it’s been open since 1912. That means East Cambridge was quite the seafood hotspot in the early part of the 20th century - you might have had a hard time finding alcohol back then, but it sounds like mussels were falling out of the sky. Courthouse differentiates itself from New Deal by also having a restaurant next door (which serves fish and chips, chowder, and… fried chicken?), and a selection of linguiça from the owner’s Portuguese homeland. But otherwise, Courthouse offers a similarly great selection of whole fish, fillets, and pantry staples.
