WanderingJew, my friend, this is a tough one, but not impossible.
This time of year on the Maine coast, the lobsters are hard shell, and the tourist traffic is way down,due to the weather, which eliminates the "lobster in the rough" experience.
Most places cover their expenses by changing their menu pricing to "market price", in case bad weather and poor harvesting drives up the price-this way they can continue to make a profit.
The Lobster Shack in Cape Elizabeth
http://lobstershack-twolights.com/appears closed for the season-no one answers the phone today. This is a people's choice winner in the local papers.
The local waterfront places, Boone's Restaurant and Demillo's
http://www.dimillos.com/floatingrestaurant/map.html will offer classic sit down lobster meals right on Commercial St. (waterfront)in Portland.
Bayley's in Scarborough may only be serving lobster rolls
http://www.bayleys.com/.
One of the guaranteed twin lobster special restaurants is the Cascade Inn, on Rt. 1 in Saco, but again, I am not sure about the specials, due to the offseason.
http://www.cascade-inn.com/ An alternative suggestion is the Christmas Prelude Celebration in Kennebunkport [url]www.christmasprelude.com[/url]
In this area are many more lobster places that might be open-check out this page:
http://www.thefishhousecapeporpoise.com/attractions.htm The Wayfarer in Cape Porpoise serves homemade roast beef hash and blubery pancakes, and is another local favorite.
Here is an excerpt from the Christmas Prelude schedule:
SATURDAY, DECEMBER 4
11:00 AM – 2:00 PM – Lobster Roll Luncheon, clam chowder, hot dogs, chips, homemade pies and beverages. First Congregational Church, Corner of Arundel Road and North Street
4:30 PM – 8:00 PM – Downeast Lobster Bake. Featuring lobsters, steamers, hamburgers and hotdogs. Washington Hose Fire Company, Route 35, Lower Village
The accomodations in the area may be a bit harder to get because of this festival, however. It is the 23rd year.
If really stuck, the Bull N Claw restaurant is across the street from the Maine Diner in Wells, but mostly services a tour bus crowd.

Feel free to email Heather and I if you have any more questions.
