Guess you are talking about eating at friends for dinner as all chain restaurants offer calorie counts and im betting up to 20% of all restaurants everywhere offer nutritional info too. If less people choose not to opt at the other 80% more will follow. If a family member cooks it you surely can know how it was prepared if you arent preparing.

As for and noted I eat out always a health-ish chains. The AI is getting the info directly from their sites, so taking a pic the AI knowing my location/what restaurant and matching it with pics restaurants post ..it will be seamless vs. having to now pull out my phone and tell GPT or take a pic.
