At the Brussels diving school NEMO33 you can enjoy a full meal underwater, which requires going for a dive and then entering into a protected pod.
The location has a 16-foot deep pool with a pod at the bottom, and if you swim down and get inside other divers will serve as waiters and bring in food that has been protected from the elements.
The food on the menu offered is lobster, Foie Gras, and champagne, because how could the meal be ordinary if the circumstances are not.
Of course, prior scuba diving experience is required, but it is located inside of a diving center so if you need to learn you can do it there before diving down for the unique meal.
The cost of the experience is $105 per person.
