A waitress with a cheerful smile serves a classic burger and milkshake in a retro 1980s diner setting, captured in hyper-realistic, photo-realistic detail. The setting features vibrant neon lights, checkered floors, and chrome accents, evoking a nostalgic atmosphere. The scene is lit like a studio photoshoot with high resolution and a shallow depth of field, focusing sharply on the waitress's friendly expression and the beautifully arranged food, while the lively background softly blurs, enhancing the sense of depth and authenticity.
