This has meant many food providers have had to get creative, including increasing the presence of so-called dark kitchens, also called ghost or cloud kitchens. Restaurants, caterers, and fast food chains can rent out space in facilities designed to make food specifically for delivery or catering. Wendy's has been an adopter of ghost kitchens around the world, and Chick-fil-A has also used them in the past. A recent TikTok noted a few other popular "ghost kitchens" and Denny's announced this week that it would be testing two new "virtual brands" this year. It's worth noting that some people have mixed feelings about so-called "ghost kitchens," specifically ones that have different names than their parent restaurants.
