Imagine an immaculately clad steward, wading out of the surf on some idyllic beach to serve you Sevruga caviar from a silver salver? Seabourn call it Caviar in the Surf. On some of their tropical cruises it is the perfect complement to a silver service beach barbecue while lobster sizzles on the grill and guests swizzle all manner of cocktails or quaff champagne. On other cruises, guests enjoy a lavish "sailaway" caviar buffet in the Observation Lounge atop the ship.
