The Purgatory Bar is a popular dance club and bar on the Citadel, though it is not known by Avina to be a registered nightclub. Various citizens from all races often visit the bar to drink and dance in order to detach themselves from the issues of the war with the Reapers.

Should Shepard get drunk in Purgatory, the Commander wakes up after sleeping off the alcohol next to Aria in the VIP Lounge. If Shepard gets drunk again, the Commander will end up in the elevator outside of Purgatory. At this point, Shepard will be unable to use the bar until the Commander leaves the area and returns.

Aria uses Purgatory as her base of operations after Omega was taken by Cerberus. She loathes the club, ironically calling it hell, and comments about its inferiority in comparision to Omega's Afterlife Club. However, she can still be found here after retaking Omega.

The Afterlife Club is a nightclub on the mercenary-controlled space station Omega. It is comprised of three floors, with the first floor resembling the layout of Chora's Den on the Citadel, featuring a large circular bar with asari dancers performing atop the center section. The second floor features a large circular opening in the center, above which more asari dancers perform on a large ring suspended from the ceiling and surrounding a large purple holographic cylinder that extends all the way to the ceiling.

Around the outer edge of this floor is an elevated section with holographic images along the wall and booths in which most patrons of the club spend their time. At the back is a private and well guarded lounge from which Aria T'Loak, the asari ruler of Omega, observes. The third floor consists of a balcony circling the entire edge of the club featuring flaming torches on the outer edge and provides a complete view down to the second floor.

Afterlife also has a section reserved for VIPs. It has a back-alley bouncer-protected entrance where people can get in with a namedrop passphrase.

Chora’s Den is a gentlemen's club on the Citadel, located in the lower section of the Wards near the Markets. Its layout consists of a circular central bar, with booths placed along the perimeter of the room. It also contains a storage area and small warehouse in the back, along with a manager's office in the very rear.

The club usually has many patrons, and lively music. The highlight of the club is the asari dancers, who offer private shows—Commander Shepard has the opportunity to watch a show in an empty seat. Compared to Flux, Chora's Den is described as "livelier but deadlier".

In 2183, Chora's Den is owned by a local crime lord named Fist.
