Archer: first to arrive, due in part to T’Pol and her nudging. He’d bring sweet tea. Chef, despite being the singular most popular person that everyone knows and loves on Enterprise, would be unable to attend. So Archer would bring whatever he prepared.

Burnham: she would politely decline the invitation. She would be too busy saving all of space-time (again) or off doing negotiations that only she could attend. Besides, it’s not her party, but she will cry if she wants to.

Kirk: He’d definitely bring Romulan ale. Every party should have Romulan ale. And, and a cold dish, because dishes are best served cold. And it’s very cold…in space.

Harriman: he’d miss the party because he thought it was Tuesday. He thought all functions were on Tuesday.

Garrett: oddly, she would miss it too. Her last communique said she was en route, but then she suddenly vanished, without a trace.

Picard: wine for the drinkers, tea.earl gray.hot and tea.earl gray.hot.decaf for the rest. He’d also be the first to leave, but he’d be discreet. In the 21st century, we’d call it “ghosting.” But he’d beam out whilst visiting the loo (which is an odd way for a Frenchman to refer to the toilet).

Sisko: blood wine, for sure, and some of that jambalaya, made from switch and not that replicated stuff.

Janeway: she’d try to make a family recipe, but despite being an engineer, she still manages to burn things in the replicator.

Riker: home made pizza, which would pair nicely with the Chateau Picard wines.
