In the magma chamber of a volcano in Iceland
The Thrihnukagigur volcano, in the southern peninsula of Iceland, might be dormant, but setting up for dinner in its cavernous magma chamber is still a thrill. According to the guides at Jacada Travel, one bespoke operator that can coordinate the experience, the space is large enough to hold three full-sized basketball courts or the Statue of Liberty tilted on her side. But it'll be all yours - for a meal entirely of your design.
Underwater in the Maldives
How about sharks for dining companions? That's what you'll get at Ithaa, the underwater restaurant at the Conrad Maldives Rangali Island resort. On the menu are such dishes as saffron champagne risotto, mascarpone and truffle dumplings, and lobster carpaccio, among other luxe-leaning dishes.
In an oyster farm in Tasmania
Anyone can book a tour of the Freycinet marine farm, which harvests Pacific oysters in the Tasman Sea. But stay at Tasmania's most luxurious hotel, Saffire Freycinet, and you'll be invited to a table to stand knee-deep, as a culinary guide shucks the freshest bivalves you've ever tasted - pulled straight from the water.
In a limestone cave in Italy
Back in the 1700s, Italian nobility would dress up up to dine cliffside at the summer cave at Puglia's Grotta Palazzese, now a tried-and-true spot on the global tourist map for its postcard-perfect views. Here, the catch of the day comes with a side of sea spray from the Adriatic below. Be prepared to arrive early - You'll have to manoeuver through ascending and descending cobblestone stairways just to reach the hostess stand.
