Guests fiddling with their phones is not QR-dependent from what I experienced.

Also, waiters can be helpful, and friendly even when there's no paper menus. In my current city most restaurants are QR-enabled, and they serve food as nicely (or not) as paper-based. Absolutely the same experience except how you looking into menu. I just stopped noticing the difference.

EDIT: Maybe important note that I'm neither in US, nor an EU country.
