The Signum restaurant is attached to the Cubo appartments (all highly recommended) and offers both Mediterranean cuisine and sushi. It has both inside tables and tables on a ground floor terrace and a 2nd floor terrace with stunning views of the Bay of Naples. We ate the Mediterranean cuisine of Chef Anna - beautifully fresh and delicately seasoned seafood starters, homemade ravioli to die for - and a lovely seafood spaghetti. All the food is prepared simply with excellent flavours, and much comes from the owner's garden. The pastries and cakes served both for dessert and for breakfast were also delicious. Budget on about 30 euros per head.
