The Crew Lounge has huge picture windows offering a stunning view of space in front of the ship; this is particularly striking at warp. The room is often used for diplomatic and social functions and is staffed by a dedicated crew. It has a manned, fully stocked bar as well as several replicator modules. There are several table and benches located throughout the room, some with interactive games.
The Sovereign class crew lounge was seen in Star Trek: Insurrection and a deleted scene in Star Trek: Nemesis. It was the Voyager mess hall set redressed.
