The pungent, open-air Maine Avenue Fish Market is a local landmark. No-nonsense vendors sell fish, crabs, oysters and other seafood so fresh it's almost still flopping. They'll kill, strip, shell, gut, fry or broil your desire, which you can take to the waterfront benches and eat blissfully (mind the seagulls!).
The surrounding area is being heavily redeveloped, but supposedly the market will remain as is.
