This comment and the one below it, also about China[1], should be higher up. It was very convenient to be in a restaurant and have a digital menu in a standardized format. Of course, it required a number of factors to align: all interactions were through one of two apps (WeChat or Alipay), the menu layout was standard, font size was not tiny (no zooming necessary), cell and/or wifi coverage was not lacking. There was also a choice between having a menu portal and just a payment portal. Street food vendors usually had a laminated QR code tacked to their cart and you could scan and pay without the vendor needing to ever handle cash, which made for a more efficient processing of the line. It certainly wasn't a perfect system, but it was a lot better than the US, where restaurants have multiple different menu layouts, some are PDF, some let you pay via mobile, etc. The lack of relative uniformity makes for some positive but many negative user experiences.
