I built a web-app MVP which is basically a QR menu app, as a web-app with URLs for each menu in the format webappDomain/RestaurantName, for example my demo is at tearounder.app/TheLoremIpsum

My MVP solves quite a few of the grumbles people mention, and other grumbles either dictate the sort of venues that shouldn't adopt this tech, or show why this tech should always be as well as traditional service not "instead of". (There are also some grumbles that require more development to iron out)

Stuff my MVP does that solve grumbles mentioned in this thread: - simple URL format means you can use the URL rather than scan a QR code. If the restaurant name is long, a shorter version of the name should be used for good UX. I see QR codes that point to those URLs, as a good and easy option to provide for those people who now expect a QR code, but not the main way to access the menu. - web based means no need to install an app (I have also met some of the basic requirements for a "Progressive Web App" so some browsers will let you save it to your device once you are on the website if you want) - I keep file-sizes low, and put thought and effort into making it load and continue functioning smoothly even over slow and patchy internet connections. There are some things I could do to improve performance and smoothness on poor connections, particularly during building up your order, but it was easy to make it so that you can browse a menu to your hearts content even if your connection drops completely right after page load. Right now data for entire menu comes over at page load as JSON (that was created when restaurant last changed their menu), all UI up to placing order is handled in one page via client side JS, then as you add items to your order ajax calls add those items to a WooCommerce cart and tapping order sends you to a WordPress/WooCommerce checkout screen. Extra dev time to make a buffered version of that system, would get the connection need down to just the pageload and checkout/pay, but with the basic setup I have right now there is also need for a connection each time you add an item. The MVP setup would also require restaurants to have their woocommerce orders page up on some device behind the bar, which is not a great UI for their needs - so a "full" version of the web-app would need a custom page, and only use WooCommerce as a back-end if that made sense for that restaurant.
