Photo of mashed potatoes with an egg yolk on top, served on a blue plate at a Japanese restaurant. The potato puree is smooth and creamy, with the eggs forming a soft center inside it, decorated with black pepper powder for coloring. It's placed on a wooden table. No other food items are visible but there are more decorations around to create a cozy atmosphere. Soft natural light illuminates the dish, highlighting its texture and color contrast with the background. A close-up shot focuses on the delicious look, in the style of a Japanese restaurant. --ar 4:3
