What should one bring to a company Christmas party?

What one should bring to a company Christmas party depends on where the party is being held. If no one specific person is holding it and it is being held at the company office, then the company itself might be providing food and drink, so it wouldn't be necessary to bring anything. If it is being held at someone's house then it might be a good idea to ask the host what one should bring. Party food such as chips/ crisps or chocolate or wine would be good items to bring for example.
