For lovers of the sweet ivory flesh of our favorite crustacean, there's a new place in town that treats the lobster with the respect it deserves. At 500 Jackson, you can tear into a carefully steamed 2-pound Maine beauty, served split for easy access to the tender tail, with the requisite melted butter and lemon (and crackers for the claws), plus a wonderful spicy pepper slaw and a cone of house-made potato chips, for $42. Or two of you can command a clam bake, which in addition to the lobster piles on littleneck clams, mussels, potatoes, corn on the cob, and spicy sausage, the whole array steamed in seaweed, for $60. Before the lobster, you can start with a creamy bowl of New England clam chowder, or continue the shellfish theme with selections from the raw bar -- maybe a chilled half lobster for $12.50, if for you too much is never enough.
