Background: Warm-toned photography of a signature dish from the restaurant, like a freshly baked pizza or steaming ravioli on a raw linen napkin.

Typography: The restaurant name "La Tana Dell'Orso" in a thick-stroked serif font in white. Below it, the slogan "Authentic Italian Cuisine" in smaller letters.

Elements: The restaurant's bear logo in one corner. Social media icons in the opposite corner. "Recommended by Michelin" seal as a mark of quality.

Proportions: 1200 x 628 px, with text centered at the top and icons in the lower corners.

Style: Warm colors, serif font and use of white space to create contrast. Conveys tradition, authentic gastronomic experience and quality.

What do you think of this design proposal? I'm open to making modifications based on your needs and preferences for the restaurant. I hope this initial idea serves you well! Let me know if you need another example.
