Strap on and enjoy the ride! Or rather, your meals! :)
The Dinner In the Sky restaurant in Belgium is definitely not for anyone with Acrophobia(fear of heights).
Once you're strapped to your seats, the diner will be hoisted 50 metres up in the air, suspended by a crane.
According to Wikipedia, The Dinner In the Sky Restaurant is called one of the world's ten most unusual restaurants by Forbes magazine.
I myself call it one of world's most exciting meals. Hope they provide airsickness bags up there.
