So "steamer" is the actually the name of a soft-shell clam? I'm so ashamed to say that after 10 years here I just found that out...I always thought it simply referred to the preparation.
Durgin Park does 'em well, of course; UOH's are always full of sand. Read the recent praise for Halfway Cafe. What about Barking Crab--are steamers one of the things they can handle, or not?
