I love this idea. However, I think it is crucial that you have some sort of demos available for people to look at on the front page.
Edit: You should also allow users to change fonts / text colors, as well as section background colors. I would be very annoyed if every single restaurant website looked exactly the same. I'd also recommend allowing them to upload their logo as an image.

Also, let them download their menu as JSON maybe?
