The Cambrian Tap stands on the corner of St Mary Street and Caroline Street (Chip Alley) in the heart of Cardiff city centre — a craft-beer refit of a traditional pub with two changing real ales, a garden, Wi-Fi and a dog-friendly welcome. It's a busy city-centre spot that regularly hosts live music alongside quiz, comedy and karaoke nights, making it a handy mixed-genre stage for both originals and covers. A house PA, guitar and bass amps and a couple of vocal mics keep things plugged in. Generally open noon to midnight daily, with later hours toward the weekend. Part of the S.A. Brain estate.
