Officer's lounge

The officer's lounge was a recreational area aboard Federation starships and installations. It was also used for official functions such as receptions and dinners

In 2285, Admiral James T. Kirk and Fleet Admiral Harry Morrow had a meeting in the officer's lounge at Starfleet Headquarters. The lounge was visited by several Starfleet officers and their companions, such as an officer's wife. 

During the V'Ger crisis in the 2270s, Kirk had a talk with Spock and Dr. Leonard McCoy in the officer's lounge shortly after the USS Enterprise's refit.
