Throwing a large party can be a little tricky, especially if you want to contain your guests in a certain area and don't want them all hovering over the food table, making it difficult for interaction. A neat suggestion by Apartment Therapy is to use the food to highlight where you want your guests to hang out and mingle.
There's a natural tendency for people to hover near the kitchen, and if it's overly crowded, this can impede good conversation or comfortable social interaction. Putting snacks in different locations throughout your space can help disperse the crowd a bit.
The possibility of food spillage in more that one area of your home will drive you nuts, but it is otherwise a good idea if social interaction is at the top of your list.
