"Design a large, modern restaurant with a coastal city theme, offering a serene and inviting atmosphere. The expansive space features a soothing color palette of ocean blues, soft whites, and sandy beiges, with natural materials like light wood, stone, and rattan dominating the decor. Incorporate high ceilings with linear lighting fixtures to create a dramatic yet calming ambiance, complemented by large, open windows or sliding glass walls that flood the space with natural light. The layout includes spacious seating arrangements with a mix of cozy booths, elegant tables, and lounge areas, all designed for comfort and flow. A central, grand counter or bar with a sleek marble or light wood finish serves as the focal point, surrounded by minimalistic yet stylish nautical-inspired decor, such as wave patterns, abstract oceanic art, and greenery in modern planters. The overall design should create a luxurious and airy environment, perfect for an upscale dining experience."
