Is MDR open for lunch on embarkation day on Carnival Splendour?

Sailing on Splendour on 10th November.   Have sailed on her once before just before Covid but can't remember if we could eat lunch in main dining room when we boarded or if only the bistro was open.

I just got off and didn't see it listed on the day. But worth the ask.
