Interesting Lunch in Portsmouth, NH?
My fave is the Oar House. It's consistently good and is a Portsmouth staple. If it's warm, definitely sit on the deck- it has a great view of the harbor. You wont be disappointed.
Also something to check into is the Dunaway, located in Strawberry Banke. It's been getting poor reviews from hounds lately, but the location and surroundings are quite interesting. I was just in Portsmouth over the weekend and tried Black Trumpet and although it is quite surely one of the better eateries in the town, I wasn't that impressed by it- considering the raves it gets on this board. That being said, BT is better for dinner, not lunch since it's a dark wine bar.
By the way, if you're in Strawberry Banke at lunchtime, they have some pretty good stuf. If you haven't checked out their site, you should, They have a whole page on where to eat both in the museum and in Portsmouth:

We had a great lunch at Chiangmai Restaurant. It has very interesting Thai food, (much better than the many Thai restaurtants we've tried), and a very nice atmosphere. It doesn't has scenic views,but is right in heart of downtown on Penhallow St, easy walk to everything -- harbor, shops, Prescott Park, Strawberry Bank , etc.
