Having read many Maine and North Shore postings as reference for a trip up the Maine coast to BH and Acadia and another to Rockport, MA, it seemed appropriate to provide feedback based on the Chowhound notes.
SEAFOOD: Bar Harbor area -- Beal's appears to have closed its doors; Dreamworld across from campground in Trenton, I think, not too bad lobster pound; Chart House in BH good enough lobster roll and OK chowder.
Wiscasett -- Sea Shack rules!
Rockport area MA -- Essex Seafood is worth the stop. The BEST of all the chowders. Farnham's was good. Very good clams in both places. The Greenery in Rockport sells "chowder," which, strictly speaking, it is with potatoes but NO clams I could distinguish. BAD chowder but good sandwiches. Flav's was good enough but unimpressive. The old Blacksmith Shop is under new ownership. Wonderful meal built around $19.99 delicious twin lobsters and nice, soft jazz for ambiance.
ICE CREAM: BH -- the most appalling ripoff at Ben and Bill's (?) in town -- $4.50 because I asked for a large waffle cone! Mediocre ice cream for all it's touted as homemade.
Southwest Hbr. -- little shack off the main street behind the village parking lot. Worth the stop.
Ellsworth -- Blueberry Hill. Stop even if you've just had breakfast. Try the Moosetracks.
Dresden -- Here's the Scoop is good.
Damariscotta/Wiscasett/Boothbay -- can't beat Round Top.
Rockport, MA -- Sundays on Bearskin Neck -- Yuck! Actually asked for money back. The ice cream was filled with crystals indicating refreezing. The place diagonal to it was really good.
