Brewhouse sits on St Mary Street in Cardiff's Old Brewery Quarter, occupying part of the former S A Brain brew house — a multi-level space where a passageway off St Mary Street opens into a large room with a bar, a stage and a glass roof hung with musical instruments. It bills itself as Cardiff's No.1 live music venue, with live bands seven days a week from around 5pm until late across a range of genres. Add a balcony, a sun terrace and dedicated party areas, and it's a go-to city-centre spot for both locals and visitors after food, drinks and entertainment. Run by Croeso Pubs.
