Even at my most gluttonous, many years ago, I would order maybe a single takeaway every other week, and when I did that, I'd want to be in complete control to browse and try new things. The only use case I can see for AI is as an alternative to traditional search to work out what some unknown ingredient is, however if I recall, most takeaway apps are just pictures with a name.
People who eat fast food more than once a week need to seriously assess how bad this food is for them. It's overly salted, oily and greasy junk with next to no nutritional value. And for what is it, it is ridiculously expensive. The people that eat it often are stuck in a trap.
For less than half of the cost of the lowest value takeaway (around £20.00, although I've seen people carrying bags with receipts up to £50!), you can buy a whole chicken, potatoes and vegetables, which can cover up to 3 or 4 meals. £10 for 3 meals or £20-50 for 1. You just need to put things in ovens and pots and wait, the same as you have to tap on your phone and wait.
