Prices for lobster in the rough tend to be a bit more expensive around Kennebunkport than at other casual lobster joints further up the coast. But if you can't wait and are willing to pay the price, Nunan's Lobster Hut (tel. 207/967-4362), on Route 9 north of Kennebunkport at Cape Porpoise, is a good choice. It's a classic lobster shack, often crowded with diners and full of atmosphere, which helps make up for sometimes lackluster food and disappointments such as potato chips (rather than a baked potato) served with the lobster dinner. It's open daily for dinner, starting at 5pm in summer.
