The Treasury is an independently owned café-bar and restaurant on Catherine Street in Plymouth city centre (PL1 2AD), open since 2003 and set in a striking former 19th-century city treasury building — the original walk-in strong room still survives beneath high, ornate ceilings. The standing capacity is around 100. The venue runs an eclectic entertainment mix, with acoustic live music on Fridays and DJ nights on Saturdays, plus a hireable function room and full-building hire for events. Super-premium cocktails, craft beers and continental lagers sit alongside a modern, seasonal food menu. A house PA, guitar amp and piano are provided, and both originals and covers are welcome.
