For something fully upscale, head to the five-diamond restaurant at The White Barn Inn, a Relais & Chateau property. The seasonal bistro menu is presented as a four-course prix fixe. But for something a little out of the ordinary, ask about the "Crustacean Crawl." For $300 per person, you'll go on a six-mile bike ride with grand chef Jonathan Cartwright, stopping at multiple under-the-radar seafood spots and then choosing your own lobster from a local fisherman, which Cartwright will cook for you that evening.
