What's On in Cardiff
Saturday 19 September 2026 · This weekend · City guide
Cardiff is turning it up to eleven this Saturday, with something genuinely brilliant happening at every corner of the city. From a West End smash landing at the New Theatre to a raucous rugby afternoon at the Arms Park, the Welsh capital is in full swing — and come nightfall, the clubs and music venues take over with equal gusto. Whatever your Saturday looks like, this city has a version of it worth showing up for.
Highlights

Operation Mincemeat: A New Musical — One of the most inventive and beloved British musicals of recent years rolls into the New Theatre Cardiff, and you can catch it twice — at 2:30pm or 7:30pm. Based on the audacious World War Two deception operation, this show is wickedly funny, surprisingly moving, and packed with musical invention that defies easy categorisation. If it passed you by in London, here is your chance to see what all the fuss was about — check the website for ticket prices and availability.

Cardiff Rugby v Exeter Chiefs — Cardiff Arms Park is one of the great rugby atmospheres in the world, and a home fixture against Exeter Chiefs is exactly the kind of afternoon that reminds you why live sport is irreplaceable. Kick-off is at 3:00pm, meaning you have time to soak up the pre-match buzz on St Mary Street before the roar of the crowd pulls you in. Head to the Cardiff Rugby website for ticket details and do not leave it too late.

Robert Arkins Commitments — Robert Arkins — the man who played Jimmy Rabbitte in the original Commitments film — brings the spirit of that legendary story to The Globe at 7:00pm, and it promises to be a soulful, feel-good evening of live music that will have you on your feet. Expect the kind of raw, joyful energy that made that film a classic, delivered by someone who lived it. Check the website for pricing and do not underestimate how good a night this could be.

Loveletter / Monochrome / Derail. — Clwb Ifor Bach — Cardiff's most cherished independent music venue — hosts a three-band bill of homegrown talent at 7:00pm, and at just £10 this is one of the best-value nights in the city this weekend. There is something genuinely electric about catching emerging artists in this intimate basement space, where the ceiling feels low and the energy feels enormous. Get there early, stand near the front, and remember their names.

Bingo Jamz Cardiff | 2026 — Bingo Jamz has taken the concept of bingo, stripped out the village hall quiet, and replaced it with a full-on party atmosphere at District Cardiff from 7:00pm. For £19 you get an evening that mixes the communal thrill of calling your numbers with live DJs, prizes, and a crowd that is absolutely here to have a good time. It is daft, it is loud, and it is exactly the kind of night out that becomes a story you tell for years.
Highest Primzahl on Mars — If you like your Saturday night with a side of something heavier and harder to categorise, Fuel Rock Club is the place to be at 7:30pm. Highest Primzahl on Mars is the kind of name that tells you this is not going to be background music — expect volume, energy, and a room full of people who came specifically to be transported somewhere else entirely. Check the website for ticket details and prepare accordingly.
