Belgian novelty restaurant Dinner in the Sky is aptly named: A crane hoists the guests, their table, and the wait staff 180 feet into the air for a 90-minute meal aloft. Founded in 2007 by a marketer and a bungee-jumping impresario, the company has expanded into 47 countries. Most of the food is prepared on the ground, where up to 44 guests sign liability waivers before being strapped into seats around two tables for the duration of the meal; guests are encouraged to use the restroom first, and the foods are chosen to avoid choking hazards.

Ithaa (below) is the world’s first undersea restaurant, an acrylic bubble located 5 meters under the Arabian Sea in the Maldives. Guests enter via a spiral staircase; the 5-by-9-meter main dining room seats 14 and offers a 270-degree view of the surrounding sea (including some of the same seafood that’s on the menu). Lunch for two costs around $120; that’s cheaper than dinner, and the view is best when the sun is shining.
