What would you call a food service model that eliminates a conventional dining space?

A food service model that eliminates a conventional dining space is referred to as a headless restaurant. This concept is designed to streamline operations by focusing on food preparation and delivery without the need for a physical space for diners to eat in. Headless restaurants often leverage technology and delivery services to reach customers, allowing them to operate in a more cost-effective manner by minimizing overhead, such as rent and staffing for in-house dining experiences.

In the context of the other options, traditional dining involves a physical space where customers sit and enjoy their meals, fine dining typically refers to a full-service restaurant experience with a focus on high-quality food and service within a conventional dining environment, and a café usually provides a space for customers to dine in, socialize, and enjoy a variety of light meals and beverages. Thus, these options do not align with the headless restaurant model, which is characterized by its absence of a customer-facing dining area.
