Otium

Located on the Blue Nile Boat in Zamalek, Otium is an open-air lounge, restaurant and club, whose website describes the venue as fresh, funky and floating. Otium is actually an old club with a new name; in a previous life this hot spot was called 'Opium', but that changed when a wealthy Saudi bought the boat and objected to the drug reference. The new name is slightly more esoteric, since 'otium' is actually a rather abstract Latin term referring to leisure time, though, ironically, it also sometimes refers to retirement.
