The Ombelico del Mondo (yes, belly button of the world), is a large bar on two floors, which is right in the middle of the beach at Marina Centro. They serve excellent food and cocktails and are open during the day and at night. It is a great opportunity to take a look at the beach from high up (and the one of the only places from where you actually can). It is a good place to go before the disco or for an aperitif on the beach!
