I think theres nothing wrong with it, provided its not too much. One of the few things the country right now offers is good food, and honestly thats the only thing I look forward to apart from visiting family when Im back. I know what you mean by ppl dying with hunger, but you have to realize that eating outside sometimes brings a nice change and you dont get sick of eating inside, and it adds a little ambiance and social outgoingness to your life.
Yes thats another aspect! But I always feel guilty when I dine out.
