Fried Oysters in Boston?
Some of the best fried oysters I've ever had was the first time i went to McCormick & Schmick in the Park Plaza. Those were amazing. I know everyone loves Neptune's but the one time I had them there, there were almost too lightly fried. And I wasn't a fan of that sauce drizzled on it.
FWIW, the preparation for the fried oysters changes now and then--last I had them they were laced with pickled tongue, making for one of the most winning dishes on an endlessly fascinating menu.
I imagine, though, if someone wanted plain old fried oysters without the frills, they'd do it.
The fried oysters at Neptune Oyster on Salem Street in the North End (our little Italy) are highly regarded here. Generally speaking whatever you order at NO you can't be wrong, It is pricey, but you do get what you pay for. If you let us know if you will staying in Boston proper or venturing to other places, that might help you get a better sampling of reccomendations.
