About 400 people gathered to toast its best-known rum, Havana Club, but not with Cuba libres, mojitos and daiquiris in hand
Some 4,500 guests are expected for the 10th anniversary Dinner in the Sky at Brussels' Atomium, a complex of steel spheres and walkways in the form of a crystal that has become the city symbol since being built for the 1958 World's Fair.
Each year, 10 chefs cook on the platforms suspended in the air around the Atomium and serve guests seated at adjacent long tables.
The Dinner in the Sky runs from June 1-5. Organizer David Ghyssel, who conceived the idea in 2006, said selected partners had already staged it in 56 other countries including the United States, India, with more to take part in coming months.
