I have no idea which restaurants your frequent but take it up with them, not me. having a url written out http://restaurantname.com/menu on a sign that you can take a picture of and click on is functionally the same as a having a qr code that links to the exact same url
Having a short url like restaurantname.menu is not simply functionally the same as a qr code. A QR code is almost meaningless for me to look at...all that it says is that that there is a code hidden within these dots and I maybe can infer that the code contains a url to a menu (and maybe contains random tracking stuff). But restaurantname.menu in text communicates to me that these letters are almost certainly a url for a menu for restaruantname, and it is something that I can verbally say to the other people at my table and remember in my head.
