Ithaa

Ithaa, which means mother-of-pearl in Dhivehi, is the very first undersea restaurant in the world located 5 metres (16 ft) below sea level at the Conrad Maldives Rangali Island in Alif Dhaal Atoll in the Republic of Maldives. 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 April 15, 2005. Food served in the restaurant has evolved over the years and is now best 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.
In April 2010, to celebrate the restaurant's 5th anniversary, it was made possible to sleep in Ithaa for the night if the restaurant is not booked for dinner. The restaurant is also used for private parties and weddings.
