TBF the food places here that have photos on the menus are either chain restaurants or really bad fast food. In the latter case, the photos are flat, grey and unappetizing. (Because food photography is hard.)
Good restaurant in my locale do not have photos of their food.
I suppose the AI possibilities mean that the bad fast food places will start having decent (fake) photos which doesn’t really make that much of a difference to me.
Here in Bielsko Biala (southern Poland) I see the same in few pubs, never seen on menus though. Shops seem to be creating lots of marketing images as well with AI and it just looks...off. In any case doesn't make me want to enter the place.
