Dinner in the Sky is an event series that began in Belgium but has been featured in 45 countries across the world. Customers sit down to a gourmet dinner catered by guest chefs as they're hoisted hundreds of feet in the air by a crane and strapped in with a seatbelt. You can look into hosting an event yourself here.

Perched more than 7,000 feet above sea level atop the most remote peak of China's Hua Mountains is a teahouse that supposedly serves some of the best tea in China. However, unless you're an experienced hiker, you should not attempt to climb the "Heavenly Stairs" that have been carved into the side of the mountain leading up to the teahouse. While potentially deadly for inexperienced hikers, should you make it there after all, you will be rewarded with a traditional tea ceremony served inside an ancient Taoist temple.

Forget wood-fire ovens, how about a chef that cooks your meal over an actual volcano ? That's a real dining experience you can have on the Spanish island of Lanzarote. The restaurant is known for its grilled meats, which are carefully cooked over a giant hole in the ground that has liquid-hot magma bubbling underneath. But don't worry: the volcano is dormant... for now.

As one of the most expensive restaurants in the Maldives (and for good reason!), Ithaa allows you to enjoy a seven-course, chef-curated meal 16 feet below the ocean with 180-degree views of marine life like stingrays and colorful coral. The restaurant is part of the Conrad Maldives Rangali Island hotel.

This restaurant cuts into the side of one of the most famous mountain ranges in the world, and has been serving guests for 200 years. You can get there either by trekking up the side of the cliff, or by a less-treacherous 20-minute cable car ride. The Aescher specializes in charcuterie: guests can revel in overflowing boards of meat paired with a 360-degree view of the Swiss Alps.

Located just a few feet from the pristine, white shores of Zanzibar is "The Rock," which looks more like a rickety clubhouse than an elevated dining experience. Here you can dine on very freshly caught seafood from the Indian Ocean for about $45 per person. At low tide, The Rock is accessible by walking, but during high tide, you might have to wade a bit.

Dubai is well-known for its towering skyscrapers, but the mother of all giant buildings is the Burj Khalifa, which was recently crowned the tallest building in the world. At.mosphere is its culinary gem located on the 122nd floor, were you can take in the spectacular views while dining on modern, seafood-leaning dishes.

While it is not available for casual dining, you can host private events inside this unique structure, which was first hoisted nearly 33 feet in the air as part of a Yellowpages marketing campaign. The pod fits 30 guests seated (or 50 standing), and can be rented for a cool $3,000 (food not included).

One luxury dining experience that will cost you a pretty penny ($14,000!) is a personalized helicopter ride over Iceland with a stop at the Thrihnukagigur Volcano, where a gourmet picnic awaits you after a steep descent 400 feet into the heart of the dormant volcano.

What would you want your last meal to be before attempting a perilous hike up the tallest mountain in the world? Adventurers often find themselves downing a pint at the The Irish Pub at Namche Bazaar known as the "gateway to Mount Everest." The pub, which is located deep in the Himalayas, about 20 miles from Everest base camp, is actually a pretty normal dive-y pub, though the clientele may be more weather-beaten than your standard pub regular. The pizza is supposed to be the best in Namche.

La Mesita de Almanza may not be located on the side of a mountain or inside of a volcano, but it can be found on one of the most isolated islands in the world. Tierra del Fuego is nicknamed "the end of the world," and is one of the southernmost places you can visit on planet Earth. Quiet ferry rides and 75 miles of unpaved gravel roads (with no gas stations along the way) will get you to Almanza, where the town's population hovers around 20, and the fresh seafood is renowned.

At the Freycinet Marine Farm in Tasmania you can get really up close and personal with your dinner. In fact, a complimentary package includes a lavish oyster dinner in the middle of the oyster farm. Guests trek out into knee-deep waters to dine on the seafood the farm is known for.
