A new restaurant has opened in Japan with a view to introducing Japanese eaters to the virtues of mayonnaise. The Mayonnaise Kitchen offers a range of dishes that swap traditional Japanese flavourings such as soy sauce for mayonnaise. Restaurant goers can opt for mayonnaise with celery, Chinese noodles, or even a mayonnaise fondue. For the more adventurous, dinner can be washed down with a mayonnaise cocktail.
