On 42 rolling acres right by the Thames River, this Georgian-style inn is best known for its spa, which offers an entire spectrum of skin-care regimens, body treatments, and fitness classes. Done up with country-style furnishings, the rooms have four-poster beds, wood-burning fireplaces, and CD players. The restaurant serves tasty, local, health-conscious fare. Try the seared grilled swordfish with parsnip puree and rock shrimp ragout—it's only 375 calories, so you can
splurge on dessert.
