Ehhhh, a smartphone with a common "food" filter and a decent angle on the food does a fairly good job these days. The small sensor actually gives just the right amount of depth of field, whereas a big camera would have to stop down or focus stack anyway.
I agree with the sentiment though. Running a business is hard; they only have so much energy, so corners have to be cut, and they clearly tried to cut the media budget they'd need to stage every meal on the menu.
