At its best, a menu can be a nice leather "book". At its worst, it is a one page plastic menu that has been touched by hundreds of people before you and never cleaned, it is also probably ruined or broken on the corners and in the middle, and has also a lot hand-made corrections to ingredients and prices that makes reading it way more frustrating.
At the same time, a digital menu can be easy to navigate (with sections based on first courses, second courses, appetizers, etc.), it can show you the pictures of the food you're going to order and, sometimes, allows you to order without waiting for someone.
Even at their worse, I still prefer the digital version as it is more hygienic and I don't have to wait 15 minutes for a waiter if they forget to bring one to the table (and then we also have to share that between 6 people).
