The Gremlin Club is a town-centre members' club on Guildhall Square in Carmarthen that is open to non-members as well as members — so a performer does not need to be signed up to play or to come and watch. There is a stage in the room, cabaret most Saturday nights, and a dedicated Sunday open mic that the club runs its own page for. It keeps long hours (from 10am to midnight most days, through to 1am on Fridays and Saturdays), pours cask ale including its own house beer Sharp's Gremlin Gold, and puts the major sporting fixtures on screen.
