1. Weird & Wonderful Restaurants Of The World

2. Ithaa Undersea Restaurant, Maldives
Jacques Cousteau meets Blue Water Grill at the Conrad Maldives
Rangali Island’s Ithaa, the world’s first aquarium-style
underwater restaurant, set 16 feet below the surface of the
Indian Ocean between a lagoon and coral reef.
Those lucky enough to score one of the dozen seats can dine
with the fishes, surrounded by clear acrylic and 180-degree,
below-water views.

3. The Clinic, Singapore
Singapore now has its own molecular gastronomy restaurant to
join the ranks of Heston Blumenthal’s Fat Duck and Chef Ferran
Adrià’s El Bulli, where food takes the form of weird science
experiments: foams, liquid nitrogen, even an ultrasonic mixing
technique used to create unique emulsions.
Only The Clinic has gone a considerably bizarre step further.

4. Dans le Noir?

5. Dinner in the Sky
Elevating foodies to new heights over cities all over the globe
like Paris, Brussels, and Dubai, Dinner in the Sky offers 22 seat-belted
guests a chance to dine at a seven-ton table attached to a crane, hovering
165 feet in the air.

6. Modern Toilet Restaurant, Taipei

7. Fortezza Medicea, Volterra, Italy
This may be one of the world’s most difficult reservations to
secure. After all, not even New York’s Masa requires a thorough
background check and the "OK" from Italy’s Department of Justice.
That’s because, in addition to serving fluffy gnocchi and robust
Chiantis, most chefs, waiters, and sommeliers are also serving 25
to life.
