It's been hit and miss. I've had good and bad. The best I've found are;
1. QR code to PDF of full actual menu. If they direct you to a HTML page is usually awful and is accordion based mobile UI that involves a bunch of clicking in and out. A PDF can be zoomed in/out but all the content is right there.
2. QR code to pay. This is great when it comes on your bill and you can just pay and leave. However, if it allows Apple pay it's very smooth. Unfortunately, most of the systems involve a web based checkout flow including manual credit card entry and capturing more info than is really needed (email/phone) so they can spam you later.
