General Ratio:

• Kitchen Area: 30-40% of the total space

• Dining Area: 60-70% of the total space

For a 150 m² restaurant, this translates to:

• Kitchen Area: 45-60 m²

• Dining Area: 90-105 m²

Factors to Consider:

1. Menu Complexity:

• A more complex menu with a wide variety of dishes may require a larger kitchen for additional preparation and cooking stations.

2. Cooking Methods:

• Traditional Japanese cooking methods (sushi preparation, teppanyaki, etc.) may necessitate specialized equipment and areas within the kitchen.

3. Dining Experience:

• For an authentic experience, you might need space for features like a sushi bar, tatami seating, or teppanyaki tables.

4. Storage:

• Consider the need for storage of fresh ingredients, which are crucial for Japanese cuisine. This includes refrigeration and dry storage.

5. Staff Workflow:

• Ensure the kitchen layout allows for efficient workflow for chefs and staff to move between preparation, cooking, and serving areas seamlessly.

6. Customer Comfort:

• Adequate spacing between tables is essential for customer comfort and to create an authentic, tranquil dining environment typical of Japanese restaurants.
