Red Sector features several large rooms that can be rented for ceremonial or festive occasions. The rental fee may include any furnishings that can be supplied by the station quartermaster, though the renting party may also supply their own furnishings. In 2258 Ambassador Mollari used a banquet room to demonstrate Centauri cultural beliefs as a part of a cross-cultural exchange. Later that year a banquet was held for the League of Non-Aligned Worlds representatives, before which Ambassador G'Kar protested the Narn delegation had been seated next to the Vree, citing their horrific table manners.

In 2260, when Brother Edward dropped his bag in Brown Sector, Garibaldi later found someone trying to sell it down in the Bazaar.
The casino in Red Sector offers a variety of games where all major currencies are accepted. When he first arrived on the station, Londo Mollari would often spend a lot of his time and money in this establishment, although as he gained in power and responsibility, he found that games of chance no longer held his interest. While investigating the murder of Stephen Petrov in late 2258, a lead led Security Chief Garibaldi to a man named Devereaux, who was know to hang out in the casino. In 2259 a large contingent of Earthforce Marines briefly arrived on the station, during which time a disagreement between Private Kleist and Lieutenant Warren Keffer  led to a major fight among Earthforce personnel in this area.

A bar and nightclub in Red Sector, owned by Ock. Ock took great pride in the fact that he procured only the very best female dancers on the station, as a result the club had a sector wide reputation as a fine pleasure spot for all sentients. The dancers would perform sets in the main area and were also available to be hired for private shows. In addition to the main area, the club also features a private area in the back for high stakes games of chance. In 2258 Adira Tyree was working as an exotic dancer in the Dark Star when she met Londo Mollari. Later that year, Londo talked Lennier into to a game of cards in the Dark Star, the it ended abruptly when one of the other players, a Hurr, discovered Londo attempting to cheat. After the ensuing riot Security arrested 30 humans and aliens.
