I have asked for a paper menu in these cases and almost all restaurants have been happy to oblige. One time the restaurant let me use their ipad to see the menu.
I wouldn’t count on this, but I’m trying to give a business money. Most are happy to satisfy reasonable requests.
I was at a food court recently where one of the restaurants didn't have a menu. Just a QR. I asked, and there's no paper version available. I asked what they do for blind people and got a blank stare.
So I went to the restaurant next door. If you can't even bother to scribble a menu on a chalkboard, you're not a real business.
