Time Out says
It's open mic comedy, in a small cinema, in a reno-d pub – so, so Sydney
An iconic room in the Sydney Comedy scene, Cactus Juice runs each Monday with a guaranteed stellar line up. This cosy space upstairs at the Newtown Hotel complete with vintage cinema seats makes for an entertaining evening. The show starts at 8pm but if you arrive anywhere from 6pm you can snag yourself a $4 happy hour pizza before the show.
Comics have up to four minutes per set, and can sign up on the Cactus Juice Facebook page from 10am on Mondays (although not everyone will get up – their slots are in high demand).
