Porto Cervo's nightlife runs July and August and is the most expensive in Sardinia. The Billionaire Club, owned by Flavio Briatore, attracts international celebrities and has a strict door policy and high prices. The Ritual and Phi Beach clubs operate on beach club formats with daytime relaxation evolving into evening parties. For something more relaxed, the Lord Nelson Pub at the marina and the cafes on the Piazzetta serve drinks at more accessible prices. Outside high season, most venues close entirely.
