Full Fat Social

Full Fat Social is an independent café at 22 Mermaid Quay in Cardiff Bay, serving locally roasted coffee, brunch and small plates throughout the day, with extended evening hours on Fridays and Saturdays.

Dogs are welcome inside. Visit Wales highlights it as a particularly good spot for puppies, and dog biscuits are available on demand. The café also hosts occasional dog-friendly pop-up events, such as dog portrait sessions — check the venue's social pages for upcoming dates.

Opening hours are Sunday to Thursday 8am–7pm and Friday to Saturday 8am–11pm, making it a practical stop for morning coffee or an evening plate after a walk along the waterfront.
