Clwb Ifor Bach is used as a social centre by Welsh speaking people in Cardiff, as well as by many non-Welsh speakers.

[2] Clwb Ifor Bach is the focal point for many Welsh-medium organisations and events in the area: social, educational, sporting and otherwise.

With worries that complaints about noise would threaten Clwb Ifor Bach and The Moon Club's existence, the 'Save Womanby Street' campaign was launched by Thom Bentley and Ewan Moor.

In early 2019 Clwb Ifor Bach announced plans to take over the derelict site next door to create new 500-capacity and 300-capacity venues.

The range of music played is very wide, and includes reggae, folk, hip-hop, pop, rock, dubstep, drum and bass, house, electro, Welsh and more.

In 2014 the club started holding comedy performances from established stand up and sketch comedians, usually on week nights.
