The appallingly bad photograph below was taken on my mobile phone about 15 years ago. It shows the menu layout from the Lisbon restaurant Chapito. I have never seen any other restaurant adopt such an ingenious format. You are given five set menus to choose from (white, yellow, orange, red and green) with a suggested wine for each. But you are perfectly free to substitute any dish from any other menu, or omit a course if you want. It is a brilliant example of what is sometimes called ‘choice architecture’.

This format makes it easier to choose what to eat. But it also helps you make a better choice. You have the same freedom as if you were to select from a conventional menu of five starters, main courses and puddings, but the format also contains an additional layer of information: it communicates what dishes (and wines) the chef believes complement each other best.
