Star Castle Hotel

The best restaurants in Scilly are in its grandest hotel, which was built in the form of an eight-pointed star to defend St. Mary's against pirates and the Spanish Armada. The more traditional restaurant is inside the castle, and the other, serving a sublime four-course seafood menu, is in a conservatory built around an old vine that trails beautifully across the ceiling. (The hotel's owner is also the vintner of Holy Vale Wines.)
