Normally it's just a URL encoded in QR code, as the storage capacity of a QR code would likely not be sufficient for a whole menu. One benefit of a web-based menu is that you don't have to relabel the menu when the price change, or when you need to add or remove a menu entry. You could also make your menu dynamic and hide a meal if you're short on some ingredients.
