> Yea true most restaurants use a simple QR leading to a PDF from their menu
Most of them in my area that didn't stop using QR entirely with general reopening, IME, have dynamic menus that track tables (the one app I am most familiar with has the table number as part of the QR code), order, tab, and payment processing, etc.
Even having contextual prompts for users to identify potential food allergens relevant to the order is in one app I’ve seen.
