Would you dine in this restaurant?

This place gives the concep of a "fish restaurant" a whole new meaning.

With floor-to-ceiling glass windows, it sits five metres below the Indian Ocean in crystal-clear blue water.

According to the Daily Mail, the restaurant is so bright, diners and staff are required to wear sunglasses.

The five-star Ithaa underwater restaurant can be found at the luxurious Conrad Maldives Hotel and provides breathtaking views of sharks, stingrays, turtles and other sealife.

A spokesman for the luxury resort on Rangali Island said: 'Using aquarium-inspired architecture, Ithaa was built to allow guests to enjoy the colour, clarity and beauty of the Indian Ocean without getting their feet wet.'

The restaurant seats 14 people and serves contemporary European cuisine in a six-course set dinner menu.

The structure cost a staggering £3m to build and weighs 175 tonnes, with another 85 tonnes of sand ballast used to weigh it down, reports the Daily Mail.

The truly indulgent Conrad Maldives Rangali resort is set across two islands and is only accessible via a 30 minute seaplane flight. It boasts 11 restaurants and bars, including the Ithaa Undersea Restaurant, 2 spas and a number of excursions including a submarine.

The Conrad is not the only hotel to go underwater: deep sea hotels have recently taken on the market with a vengeance.

Luxury lovers will be interested in Deep Ocean Technology's new construction in Dubai (above), which, It claims, will be the world's most luxurious under-water hotel. The Water Discus Hotel will have two shaped as two discs - an underwater and above-water one, which, combined will allow guests to admire the depths of the ocean while making the most of the warm climate. The hotel will house 21 suites, a bar and a dive centre and will sit at about 10-15m below the surface – which is apparently the optimum depth for sunlight and marine life.

The owner say it will be thoroughly sound-proofed and will minimise noise pollution by placing all toilets, kitchens etc. toward the centre of the structure.

It may seem like something plucked from the pages of a science fiction novel, but this isn't a new concept. First Choice Holidays provided us with a a quick round-up of the best underwater hotels already in existence, if your bank balance will allow.

Better still, Poseidon recently announced plans to replace their windows with a new acrylic material that is near optically perfect, with bonding joints of less 1mm thick and is pretty much invisible to the human eye, just to make the experience even more immersive!

However, at $30,000 per couple for a week's stay, it might be a little out of some people's price range.
