Is a menu with photos and even video worth it?

Yes, on the few dishes a photo explains better than the name, and video only where the dish moves. It is not worth it across the whole menu if the terrace will not load and the price stops being visible. Pick three dishes that raise questions and see whether a still is enough before filming. In Madrid everything is filmed and in service nobody watches the clips, but the menu is slow. Those few cards carry the photo of the real dish, and the clip only on the one that needs it.
