A year ago, when restaurants (in Virginia) were allowed to start opening up again, offer outdoor seating, etc. they had to go to disposable, one-time use menus. I noticed a number of local places that went to QR codes rather than print up a bunch of menus.

One place that went carry-out only and has continued that way, doesn't have a huge display menu and has one menu they can wipe down and let people look at; but, has the QR ode posted in several spots.
