Quick info
About Rhostio Coffee Roasters
Rhostio Coffee Roasters is a coffee shop at 16C Crwys Rd in Cathays, Cardiff, that roasts its own coffee and also works as a live music venue. The rooftop gives a 360-degree view over the city and has shelter from the rain, so the view is there even on a wet day. Downstairs, a separate seating area adds more room, and the space is large enough for working or meeting friends. The menu pairs speciality coffee with a selection of cakes, including lemon cake, and craft cocktails. Dairy-free and gluten-free options are available for those who need them. Beans roasted on site are sold to take home. The shop opens daily.

Customer Review Summary
Reviewers return above all for the coffee roasted in-house, with the Diana and Ethiopia beans singled out as exceptional, and a smooth, well-balanced espresso and a flat white topped with detailed latte art also praised. The lemon cake and a wider cake selection come close behind. Several describe the space as cozy, warm and spacious, good for working or catching up with friends, with a rooftop that has shelter from the rain and a cool downstairs room full of customers in conversation. The staff are repeatedly called kind, friendly and welcoming, and one barista is described as knowledgeable. Dairy-free and gluten-free options get a mention too. The one complaint comes from a reviewer who attended an event and found the team pedantic about the sound level, though they still rated the service great. Another reviewer notes getting a free coffee when buying beans.

“We stopped for a quickie and drank it downstairs, which was lovely and cool with loads of diverse customers in conversation. In an hour when it cools off I bet the rooftop will be full, too.”
