Here's a meal one needs to have a strong stomach for.

Some 4,500 guests are expected this week for the 10th anniversary of Dinner In the Sky in front of the Atomium in Brussels, Belgium. They will be served meals by top chefs on 10 platforms suspended 50m high by construction cranes.

At the same time they get to feast their eyes on the Atomium, a complex of steel spheres and walkways in the form of a crystal that has been the city symbol since being built for the 1958 Brussels World's Fair.

Dinner in the Sky began on Wednesday and runs till Sunday. Since the idea was conceived in 2006, the gravity-defying dinners have been held in more than 50 other countries.
