One of the oldest military defences on Plymouth's seafront, this 16th-century stone tower was built to keep out the likes of Spanish sailors in galleons, but today Peter and Debbie Constable's seductive restaurant warmly welcomes all-comers. It is an atmospheric place when high tide laps at the foot of the tower, and you're safely ensconced at a bare wooden table within the thick stone walls of the moodily-lit circular dining room. The kitchen avidly seeks its supplies from within 30 miles of the tower, then brings them together in intuitive, unfussy combinations - roast pigeon with Savoy cabbage, bacon and chestnuts, perhaps, while main courses could see Cornish lemon sole teamed with crab risotto and shellfish sauce, or rhubarb and ginger compôte as a counterpoint to the richness of roast duck.
