This is commonly mistaken to be a reference to the River Taff which runs through Cardiff, but it is actually a contraction of "Tafarn", the Welsh word for "pub".

It also hosts the freshers fayres for the beginning of term to join in volunteering, sports clubs and societies.

The main building also houses the offices of student media including the studios of Xpress Radio (which is broadcast throughout the union), the student newspaper Gair Rhydd (Welsh for 'Free Word'), Quench Magazine, and the newly developed Cardiff Union TV (CUTV).

This is built on the ethos that sport plays a significant role in the student experience, playing a role in helping to build social and support groups, keeping students active, and most importantly, offering a valuable opportunity for individuals to develop themselves.
