Online cloud kitchens, sometimes known as virtual or ghost kitchens, are a form of food delivery service in which consumers have their meals produced in a traditional restaurant kitchen and then have them shipped out to their homes or workplaces. In recent years, particularly during the COVID-19 epidemic, the idea has been increasingly popular as more people have begun ordering meals for delivery rather than dining in at restaurants. This trend has contributed to the popularity of the notion. The attitudes that customers have towards online cloud kitchens can shift depending on a number of aspects, including the convenience of the service overall, the meal's quality, how long it takes to deliver the food, how it is packaged, and how much it costs. While some clients might value the ease and convenience of placing their food orders through an online cloud kitchen, other clients might be more partial to the more conventional dining experience that comes with eating in a restaurant. Researchers used a variety of methodologies, including surveys, consumer feedback, and reviews, in order to evaluate the level of customer satisfaction with regard to online cloud kitchens. It is essential for businesses who operate online cloud kitchens to pay close attention to the feedback provided by customers and to take measures to enhance the quality of their service in order to achieve high levels of customer satisfaction.
