The first thing you have to know is that there's really no special menu for Halloween parties. And in the end, it's all just about the presentation of your regular party food.
The secret to serving simple Halloween food is food coloring. So stock up on the colors of the season like orange, green and black and let your imagination take you to that spooky place.
For example, serve some "swamp juice" by simply adding black food coloring to your beverage, but from experience - orange juice works best with this.
The same can go for your pasta, which would look unique in black or grey sauce when you serve your "brain spaghetti".
Lastly, remember that in serving party food - your priority is to make sure that they actually taste good.
Have a Happy Halloween!
