The main bar at Caius is located right in the Old Courts, just downstairs from the Hall. It's spacious, well-stocked and a great place to meet - especially as since Lent Term 2022 it is now staffed by a friendly team of students! The bar is central to the social spaces in College, adjacent to the JCR and MCR, and many students go there for a drink after Hall in the evening.

By day, the Bar can be a good alternative place to study. In exam term, it becomes an extra day-time revision venue, allowing you to enjoy cake and coffee as you cram.

Further pop-up bars in College exist in Harvey Court JCR, where it is the venue for regular student social events ("bops"), and in the two MCR areas where postgraduate students host events.
