In today's competitive marketplace, the design of a restaurant plays a critical role in attracting and keeping customers. To create a successful restaurant interior, designers must understand its technical operations - including how food travels from the kitchen to a customer's table, how customers and employees circulate, specifications for restaurant furnishings, etc. The designer must also be able to create an ambiance with color, pattern, textures, lighting, and acoustics that appeals to the restaurant owner's desired clientele.
