Thanks much, fellow chowers! Your suggestions were excellent.
We had a magnifcent meal at Terra Luna, and ate twice (something I rarely do on vacation) at Clem and Ursie's in P'Town.
I would like, however, to warn you about Moby Dick in Truro/Wellfleet. Nothing wrong with the quality of the fish we ate there, but the portions were so skimpy, we decided to call the place Moby Minnow.
