One of the city's most beloved venues, its programme spans live music, theatre, literature, comedy, cabaret and film, supporting emerging and established artists alike and working closely with community initiatives and many of Belfast's highest-profile festivals. The attached Green Room café & bar opens Thursday–Saturday with resident DJs, visual-art exhibitions and one of the largest craft-beer selections in the city across 13 taps. Office hours are 10am–6pm Monday to Friday. Note: the row's stored address_area 'Duncairn' is incorrect — the venue is in the Cathedral Quarter.

The Black Box is one of Belfast's best-loved independent arts venues on Hill Street in the Cathedral Quarter, and its open mic runs in the intimate Green Room bar. It's a properly inclusive night — musicians, poets and comedians are all welcome, each taking five to ten minutes to share a song, a verse or a few jokes, hosted by Jessie Fletcher and run in association with Mental Health Arts Northern Ireland (MHANI). It's free to come along and free to perform, with a friendly, listening crowd that suits first-timers. It runs roughly monthly, usually on a Wednesday evening (doors around 7:15pm, starting 7:30pm to 8pm) — check the Black Box's website for the next date.
