The large briefing and conference room of Deep Space 9, used for staff meetings, diplomatic negotiations and formal hearings, and the room in which the Dominion War is formally ended.
The wardroom is a long room with a conference table and tall windows looking out on to space. Sisko uses it for briefings too large for his office, for receptions and for meetings with visiting delegations.
In Rules of Engagement it becomes a courtroom for the extradition hearing in which the Klingon advocate Ch'Pok tries to have Worf handed over for destroying a civilian transport. In Statistical Probabilities Weyoun and Damar come to it to offer the Federation a border settlement.
During the war, strategy for the campaigns against the Dominion is planned there by Sisko, Admiral Ross, Martok and their Romulan counterparts. In What You Leave Behind the Female Changeling signs the treaty that ends the Dominion War in the wardroom, watched by the leaders of the allied powers.
