DITS doesn't limit itself just to meal-based events. They've hosted up-in-the-air lounges, special PR parties, and even weddings. Meals are their mainstay, though, and they host dozens of them around the world every year for those lucky enough to snag tickets before they sell out. According to the DITS calendar for the rest of this year, there are opportunities to experience them almost every week through the end of September in places like Mexico, Slovenia, Greece, Germany, and the UK. You also don't necessarily have to go up for an entire dinner -- they host brunches, lunches, wine tastings, and even cocktail hours as well -- all of which are shorter in duration, and cost considerably less per person. The marquee dinner experience itself will set you back up to $289 (though prices vary depending on location).
