Dinner in the Sky, which is developed by Events in the Sky, is a unique event designed for anyone (excluding those afraid of heights) who wants to kick their meal into high gear. You can pretty much do whatever you want, even if it's just to have cocktails or brunch.
The table is hoisted 50 meters up (that's around 164 feet) by a huge crane and is able to accommodate 22 people (all strapped in, of course) around the table, with staff on a platform in the middle (like the chef, waiter, and entertainer). The company says that "at a rate of two sessions per hour, more than 350 people could have access to this exceptional platform." Of course, if you just want a super exclusive dinner, you can just stick with a small group.
