Ithaa, which means mother-of-pearl in Dhivehi, an undersea restaurant located 5 metres (16 ft) below sea level at the Conrad Maldives Rangali Island in Alif Dhaal Atoll in the Republic of Maldives.
Here's a short clip of our amazing experience at Ithaa undersea restaurant at Conrad Maldives Rangali Island.
The 5-by-9-metre (16 by 30 ft) mostly acrylic structure has a capacity of 14 people and is encased in R-Cast acrylic with a transparent roof offering a 270° panoramic underwater view. The restaurant was designed and constructed by M.J. Murphy Ltd – a design consultancy based in New Zealand – and was opened on in April 2005, describing itself as the world's first undersea restaurant. Food served in the restaurant has changed over the years and has more recently been described as contemporary European with Asian influences.
Ithaa's entrance is a spiral staircase in a thatched pavilion at the end of a jetty. The tsunami which followed the 2004 Indian Ocean earthquake topped at 0.31 metres (1 ft 0 in) below the staircase entrance, and caused no damage to the restaurant.
