Very cool concept - thank you for sharing it! I think would be a great solution to the near-daily "what should we eat" problem.
If I could make a (not-important) suggestion, I think being able to re-arrange / categorize menu items would be useful. Something that lets you group together drinks apart from snacks as an example.
The "what should we eat" problem was a big source of tension in our household since the arrival of our first child. Too much time-consuming, too much planning effort. What changed our life (and I really mean it) is the app https://jow.com: it suggests you a list of meals for the week suited to your family and equipment, and it creates a shopping list for your preferred delivery provider. I only have good things to say about it and could go on for hours.
