What term describes restaurants that do not maintain a physical storefront and rely on delivery?

The term "headless restaurants" refers to establishments that operate without a traditional brick-and-mortar storefront. These types of restaurants often focus entirely on delivery services, leveraging online platforms to reach customers. This business model is increasingly popular due to the rise of food delivery apps and changing consumer preferences for convenience.

Headless restaurants can minimize overhead costs associated with maintaining a physical location, allowing them to focus on efficiently preparing and delivering food. This model reflects a shift in the restaurant industry towards more adaptable and technology-driven service formats as consumer behavior continues to evolve.

The other options represent different dining experiences and do not capture the essence of a restaurant that operates solely online without a physical presence. For example, casual restaurants and bistros typically have physical locations where diners can enjoy meals on-site, and fast-casual establishments focus on a hybrid model of quick service while still maintaining a dining area.
