oops... it is Fore Street, not Four Street (the restaurant in Portland). Here are reviews copied from Gourmet magazine's website for two restaurants in Portland in case you decide to stop there on your vacation:

Fore Street
Forum Building
288 Fore Street
207-775-2717

In a city that claims to be second only to San Francisco in restaurants per capita, Fore Street is the restaurant by which Portlanders measure all others. Chef Sam Hayward is obsessive about tracking down the freshest seasonal ingredients, which he roasts, grills, and bakes in a huge wood-burning hearth that dominates the room — a late-19th-century brick warehouse, used for artillery storage during World War II, with windows overlooking the port. The menu changes daily, but regulars can count on such staples as roasted mussels in almond butter, spit-roasted chicken with corn bread pudding, and local fish, baked whole. And there's always a platter of roasted vegetables and garlic mashed potatoes for sharing. (If you can't get a reservation, you can usually find a seat at the bar.) Too full for the homemade chocolates? They'll wrap them prettily in a box for you to take home.

Hugo's
88 Middle Street
207-774-8538

With its organic meats and vegetables, freshly hooked fish, and foraged wild greens, dinner at Hugo's is a culinary snapshot of Maine. Everyone in town is talking about Rob Evans's imaginative calendar cuisine, predicated on the seasons and on what's available locally (get ready for Maine pork belly, Maine lobster, Maine-raised chicken…). Spring's fiddleheads, ramps, and Solomon's seal become fall's forest mushrooms. Some months you'll find sea urchin and baby glass eels; at other times, cod cheeks and hake. Even the hand-churned butter tastes different throughout the year depending on what the cows have been eating. Like the menu, displays of local artwork in the chic, wheat-colored dining room also change regularly.

My husband and I have a week to stay in Maine, we are flying into Portland and would like to see Portland, Acadia !!, Bar Harbor, Camden, and Freeport. Also if highly recommended Ogunquit and Kennebunk. I am looking for recommendations on B&Bs and which towns we should stay in and which would be best as day trips. Thank you, I just discovered this site and I really appreciate all of the helpful info I have found on it.
