On the private island of Mustique (the exclusive Caribbean retreat of rock stars, royalty, and the world’s most discreet wealthy), Basil’s Bar is the social heart of an island that takes its privacy seriously and its parties even more so. Mick Jagger, David Bowie, Princess Margaret, and generations of the world’s most famous names have passed through Basil’s driftwood-floored, open-sided bar on Britannia Bay. The Wednesday night Jump-Up is the hottest party in the private Caribbean. Cold rum cocktails, fresh lobster, and the world’s most exclusive guest list.
