By the way, this is roughly what I made last Xmas for our pescatarian meal (these are all borrowed photos as I can never seem to take decent photos of food):
Smoked salmon blinis to start

I think we had these topped with a choice of either dill or caviar. I like that here they have done it with what looks like hot smoked salmon and radish though and I've seen slices of cucumber incorporated too.
For the main, I made Whiskey and Nut Baked Camembert (this was very rich, so you don't need a lot)

With all the trimmings, including roast potatoes, honey glazed parsnips and carrots, red cabbage with balsamic vinegar and cranberries, stuffing balls, gravy and sizzled sprouts with pistachios and pomegranate.

So, the sides were pretty traditional, but with a few little twists here and there.
My housemate made the desert, which was homemade chocolate eclairs.
We did not make it to the cheese and crackers 😞 which seems to be the case every year!
