Lucia's is a real find. Good food, great service. Small, unpretentious.
Went to celebrate a friend's birthday recently, and have returned several times since.
YUM! Worth a detour!

I second In Good Company in Rockland and Francine Bistro in Camden.

I may be the only person — at least to post on Chowhound — to have had a truly bad meal at Primo. I agree with diningsense that the food and service are not what they used to be!

Why not get off I-95 at Portland and go to Duckfat for lunch!!
Five Islands is great — just a short detour.
As for the Camden/Rockland area, Francine Bistro in Camden and In Good Company in Rockland.
Primo is over-priced and over-rated.
Enjoy!

In Peterborough my favorite is The Pearl, but it's not a good setting for a rehearsal dinner, unless you had the entire restaurant. DelRossi's in Dublin is ideal for a rehearsal dinner, good food and small private dining rooms you could have to yourself. The garlic soup and scampi app are the best ever. I also like Sunflowers in Jaffrey.

It's worth the time to go to Orleans for groceries, just go early in the day to avoid heaviest traffic. The Nauset Fish Market recommended by BlueSoup is phenomenal; you should go there for lobsters and all your fish wants and needs. Friends has great produce, cheeses, meats. On Saturday from 8 a.m. to noon you can go to the Orleans Farmers Market on Old Colony Way, just down the street from The Sparrow; it's fun and has great finds (veggies, smoked fish, fresh eggs). Cottage Street Bakery is a treat; again, go early.
Stop & Shop has a decent bakery, produce and cheese selection. Enjoy!

Woo Jung is a hike from NH, but worth it!

At cape this past week, headed for Brewster Bookstore on 6A, when I saw sign at JT's for hot lobster roll. It got my attention, but I didn't get it; I got a regular lobster roll. Absolutely the best I've had in eons, Cape. Maine, anywhere. The best! Loaded with succulent lobster, just the right amount of mayo, and a tiny bit of celery. SuperB! Can't wait to go back.

The Wicked Oyster in Wellfleet is my favorite — breakfast, lunch, and dinner! There's a nice little market in Wellfleet center. The Eastham Lobster Pool unfortunately closed, but is reopening with new owner; new name is Woody's. May be worth trying. Arnold's in Eastham has wonderful raw oysters, good lobster rolls.

Land Ho is great fun, and the kale soup is spectacular, the fried oysters very good, as are Sir Cricketts by the rotary. The Nauset Fish Market (next to Sir Crickett's) does the best lobster ever cooked for take-out. Arnold's has great raw oysters. The Wicked Oyster in Welfleet is a bit of a hike, but it's terrific, one of my favorites!

I loved PRIMO when it first opened. It has gradually gone down hill. I don't even want to go there now. It's grown too big, impersonal; the ambiance and the food, even the service is definitely not of the caliber it once was.
