I love the blueberry pie at Hart's Turkey Farm
in Meredith. Meredith is south of the White Mtns on southwest side of Lake Winnepesaukee. Hart's makes their own pies at their bake kitchen just up hill from the restaurant. The turkey dinners there aren't bad, either.
In North Conway, Vito Marcello's Italian Bistro
is a great Italian place. There is a little history to it. "Marcello's" used to be a noteworthy Italian restaurant in Rhode Island in the 1970s and (part of?) the 1980s, as well as a noteworthy mafia hangout (so you know they had to have good food!). They closed, and eventually reopened at the location in North Conway as a place called, "Bellini's". They couldn't use the name Marcello's in North Conway, as there was coincidenally already another restaurant called Marcello's up there. Now, they are renamed again, and they are operating as Vito Marcello's Italian Bistro. http://www.vitomarcellositalianbistro.com/
In Wells, Maine. the Maine Diner
is very good, and noted for their codfish cakes and Indian pudding.
I'm not a lobster fan, so I'll let othrs comment on where to go for that.
