My mother from NY (where seafood newburg was supposedly invented) says her favorite place to eat in Boston was S&S in Inman Square, because of seafood newburg. Both my eldest daughter and wife are also fans of this dish. S&S occasionally has this dish as a special, but in the past 10 times I've gone there, they've only had it once or twice. Most frustrating is that they often claim they are serving it on a particular day, but it usually turns out to be an inferior dish called seafood casserole, which is always on their menu.
Please post if you know of *any* places that serve seafood newburg. Here is what I've found:
Union Oyster House - $20 lunch, $25 dinner
Exchange Street Bistro in Malden - $27 dinner
S&S (occasionally) - around $17
Catering: several places offer it only on their catering menu... 8(
