Woodman's of Essex
Woodman's is the ultimate Massachusetts clam shack, and (possibly) the birthplace of the fried clam. I can't eat any of that, so I loaded up on Benadryl and had an order of chicken fingers. They were super delicious, by the way. Downside: apparently no A/C in the building. YIKES!
Woodman's is also featured in the movie "Grownups" and they had promotion material all over the place.
