Ghost kitchens are commercial cooking spaces that prepare food exclusively for delivery or takeout, without a traditional dine-in restaurant. They often operate under multiple brand names from a single location, allowing for cost efficiency and flexibility in menu offerings. These kitchens have gained popularity due to the rise of food delivery services like Uber Eats and DoorDash. By eliminating the need for a physical dining space, ghost kitchens can reduce overhead costs and focus on food quality and delivery speed, catering to the growing demand for convenient meal options.
