In Maldives sea 5 metres deep under water there is a restaurant called Ithaa where
people eat while watching fish swim around the restaurant which is filled with sand Ballust and is tied to four steel piles to keep it under water.
I wondered how the people got up and down to the restaurant.
I found out;
A New Zealander designed it, access is made to it by a spiral staircase which was damaged in the 2004 tsunami, you can sleep there for $11 710 a night.
