Occupying the elegant 1889 Spa Hall from which it takes its name (Ku Kuu is short for Kuressaare Kuursaal), this is Saaremaa's loveliest dining room. The wood panelling and coloured glass provide an atmospheric backdrop for a tasty menu of seafood and island produce that visits various European cuisines. Outdoor dining, immediately opposite the castle, is a summer treat.
The best of each day's catch is usually the best choice, priced by weight.
