Easy on the ISO and hold the flash please.
Here is an article about the backlash against photographing one's own meals in restaurants.
This is something I have done rarely. One time that comes to mind is during my meet-up with Lee, Helene, and Lee's friend when we had a lovely lunch in Berkeley together. It was not a distraction to other diners as we ate during a lull. I certainly can not imagine leaping onto my chair to have done so. I also snapped Alice with her iPhone not long ago while she sipped the best capuchino in town (according to Alice). But we were outside the cafe and all alone at a sidewalk table.
It doesn't seem to be a trend where I live but this is not a food mecca. I have never witnessed someone conspicuously snapping a photo of their meal. But it appears to be annoying common other places.
