Bar Elba focuses on the plights of the infamous Napoleon, who was exiled to the Mediterranean island of Elba. He took 600 of his closest pals and his fave horse, Marengo, with him, staying for a grand total of 300 days. Party. Island. With 360 degree views over some of London's most iconic buildings, and excellent transport links from Waterloo station just 1 minute away, Bar Elba is perfect for events of all kinds, whether you're looking for a reserved area for a birthday celebration, or a private terrace for corporate guests.
