How do you include legal allergens without cluttering the photos?
Only the allergens that dish contains are written, in a short line under the photo, not all fourteen on every card. The full legend, if needed, sits once at the foot, not repeated over every image. Keep the line on dishes that have something to declare and empty on the ones that do not. In Madrid every photo carries a strip of fourteen icons and neither the dish nor the price can be seen. The card shows a short line of what it does contain, and the photo stays visible.
