They're sometimes called virtual kitchens, ghost kitchens, or virtual restaurants. They're real restaurants with actual menus, legitimate websites, and social media accounts. But, there are no hostesses or waitstaff, no tables in the dining room, and no bar to order a drink. Instead, these restaurants are housed in 600-foot kitchens, sometimes larger, or housed inside another restaurant using the same kitchen and ingredients. The menu is available for pickup, takeout, and delivery via the likes of Uber Eats, GrubHub, Postmates, and DoorDash.
