Rhostio Coffee Roasters

You'll find Rhostio tucked away on Crwys Road in Cathays, the kind of spot that draws the neighbourhood's coffee nerds without trying too hard. Walking in, you're greeted with the smell of freshly roasted beans and a stripped-back interior that lets the coffee do the talking. The team here take their craft seriously—they roast on-site, which means you're getting beans at peak freshness, and the baristas actually know their stuff without making you feel small for just wanting a decent cappuccino. It's become the unofficial meeting point for Cardiff's coffee enthusiasts, students, and anyone who reckons a proper flat white matters.
