Might be because it looks generated, or uses stock images. The ramen bowl is in a perfect perspective to show it off on a menu, but it should be spilling out in the orientation it’s been placed in. It defies gravity. The burger is random and out of place, with a different art style. The same for the cat above it. The menu is also out of place and garbled, when it should be in focus like everything else at that distance.

I guess it looks disjointed and way too busy to look like someone did it entirely themselves. So people think it’s AI or at least lower effort.
