Do you offer to bring a plate?

[Shanti]

Yes I offer unless it's a birthday party and the invite says 'food provided'

If it's a party I don't expect to take anything other than a gift and perhaps alcohol (if it's a grown up party!). For a casual get together such as a BBQ, I expect to take something like a salad or a dessert as well as a bottle of wine or similar.
