Some of the food porn pics are really good! I haven't tried it much, but it can really bring out a creative side when arranging the food to compose a great image. I prefer the images with soft back focus, to really bring the details of the dish in focus. I think "Less is more" is really the way to go with food pics. But thats just the way I like it.
My personal preference for some inspiration is FoodPornDaily | Food Porn, Food Photography
