Doesn't need to be a large gathering. When I go out to an expensive restaurant with my wife, it counts as eating for entertainment. When we eat the supper I cook while watching The Flash on TV, we are also being entertained, but the awesome adventures of Barry Allen is entertaining us. The food is eating because we need to eat. The cost is different though.
And coming back from the restaurant saying "that was fun" is not an eating disorder, like originally stated by Sehachan.
