Delivery-only restaurants, also known as ghost kitchens or virtual kitchens, are food establishments that prepare meals exclusively for delivery. They do not have a physical dining space for customers, which allows them to save on overhead costs like rent and staff. This model has gained popularity due to the rise of food delivery services such as Uber Eats and DoorDash. These restaurants often operate under multiple brand names from a single kitchen, offering a variety of cuisines. This flexibility allows them to quickly adapt to changing consumer preferences and trends, making it easier to test new menu items without the risks associated with traditional dining establishments.
