"Design a modern restaurant with a coastal city theme, evoking a serene and inviting atmosphere. The space features a soothing color palette inspired by the sea, with shades of blue, white, and sandy beige. The decor includes natural materials like light wood, rattan, and stone, complemented by minimalist furnishings. Linear lighting accents the ceilings and walls, casting soft, ambient glows that enhance the tranquil vibe. A sleek counter area with a marble or light wood finish serves as a focal point, surrounded by subtle nautical details such as rope elements, wave patterns, or abstract ocean-inspired art. Large windows or open spaces bring in natural light, creating a relaxing and airy environment."
