Just found this article about an all-glass undersea restaurant on Fark.com, this looks like it would be a great once-in-a-lifetime thing to try out. I can’t imagine what a meal must run but, if you’re vacationing in the Maldives, I suspect cost is not your primary concern.
This prompted me to recall our silver-service dinner at the base of Ayer’s rock (Uluru) in Australia when we visited back in 1999. A formal meal served on formal dishware in the open desert. TrÃ©s cool. It was followed by a local describing Aboriginal legends surrounding the moon and followed up by an astronomer highlighting some features of the Southern Hemisphere night sky. His two telescopes (and the lack of ambient light pollution) allowed us an amazingly clear view of a couple of galaxies and other objects that he pointed out.
I also thought the restaurant technology looked familiar so pulled up a couple of pictures of one of the walkways that went through the Sydney Aquarium (in Australia).
