Mess hall

A mess hall is a place on Federation and Klingon starships or starbase where one can relax and enjoy a meal or a quick snack in a social setting.

It is also the place where officials, such as ambassadors of other worlds are entertained. Gatherings are also held here.

NX class
The mess of NX class ships such as the Enterprise NX-01 was a spacious dining area located at the front of the ship. To one corner were protein resequencers, beverage dispensers, and a refrigerated display case. Crew members could serve themselves, buffet-style. To one side of the mess hall was a door that leads to the captain's mess. The mess was also used for movie nights and other crew gatherings.

Defiant class
Like much of the internal spaces aboard Defiant class starships, the mess hall was compact, functional and had no windows. It was equipped with one food replicator. The mess hall could also be used for meetings with the ship's crew. (DS9: "Trials and Tribble-ations," "Valiant")

Worf often ordered prune juice in the mess hall of the Defiant. Once, he received a cup advertising Quark's. (DS9: "The Quickening", "Looking for par'Mach in All the Wrong Places")

In 2372, Dukat and members of the Detapa Council underwent blood screenings in the mess hall after being rescued by the Defiant. (DS9: "The Way of the Warrior")

Several weeks later, the mess hall was the site of a meeting between Captain Sisko, Quark and Hanok. Later, a Jem'Hadar torpedo impacted into the mess hall, but did not explode immediately. Quark and Hanok were able to defuse it. (DS9: "Starship Down")

Later that year, the mess hall was the site of a briefing session between the crew of the Defiant and Weyoun's Jem'Hadar soldiers. (DS9: "To the Death")

During the early months of the Dominion War, the crew would place depleted phaser relay power cells in the mess hall, as a sign they would never stop fighting. (DS9: "Behind the Lines")

Ixtana'Rax had the senior staff of the Defiant held in the mess hall after the Jem'Hadar briefly captured the starship in 2374. (DS9: "One Little Ship")

Quark was ordered to stay in the mess hall as the Defiant fought its way to AR-558 in 2375. (DS9: "The Siege of AR-558")


 * The Defiant mess hall set doubled as many areas aboard the ship, including sickbay and the transporter room.

Intrepid class
On the Intrepid class vessels, the mess hall is on Deck 2, Section 13, with turbolift access in the corridor outside the starboard enterance. Some ships were equipped with four food replicators, with a private captain's dining room just behind the mess hall. The dining room could be reconfigured to serve as a kitchen, as done by Neelix aboard the USS Voyager. (VOY: "Phage", "The Cloud") The USS Bellerophon's mess hall was also fitted in this manner. (DS9: "Inter Arma Enim Silent Leges")

Since replicator rations were in short supply aboard Voyager, Neelix supplemented food stocks with vegetables from the airponics bay along with food obtained from trading and scouting missions.

The mess hall aboard Voyager was host to many social gatherings, including diplomatic affairs (VOY: "Someone to Watch Over Me"), birthday parties (VOY: "Latent Image"), ping pong games (VOY: "Relativity"), and holiday celebrations. (VOY: "Homestead")

When Neelix departed Voyager in early 2378, Chell wanted to take over duties in the mess hall. The ship returned to the Alpha Quadrant shortly following, and it is not known if Chell was given the position. (VOY: "Endgame")

The mess hall also served as a makeshift sickbay whenever that facility was disabled or otherwise overwhelmed. (VOY: "Macrocosm," "Before and After," "Year of Hell, Part I," "Course: Oblivion," "Memorial")
 * The mess hall of Voyager (and the Bellerophon) was built on the remnants of the Ten Forward set of the Enterprise-D from Star Trek: The Next Generation.

Klingon Bird-of-Prey
Klingon Birds-of-Prey, such as the IKS Rotarran, the IKS Ch'Tang and the IKS Pagh. (TNG: "A Matter of Honor"; DS9: "Soldiers of the Empire", "Sons and Daughters", [Once More Unto the Breach")

In 2373, a fight involving Kornan, Leskit and Ortikan broke out in the mess hall of the Rotarran. (DS9: "Soldiers of the Empire")

When Alexander Rozhenko joined the crew of the Rotarran he was mocked by Ch'Targh and others in the mess hall. (DS9: "Sons and Daughters")

In early 2375, Miles O'Brien, Julian Bashir and Quark ate gagh in the mess hall of the Rotarran. Quark complained about the lack of a variety of foods. (DS9: "Shadows and Symbols")
