What could be cooler than taking an old, derelict block of toilets on a Victorian city-centre park, and turning into the city's coolest new coffee shop? That's precisely what mother & son business partners Donna and Alex have done, and after an extensive refurbishment that has taken almost six months to complete, they've finally opened their doors to the public. They chose to name their baby with the Welsh spelling of “block” as a nod to the building’s past as a public loo. The cafe's interior is just 90 square metres, so it's a cosy space, but there’s also additional outdoor seating on a small patio which overlooks the park. Bloc is fast becoming our favourite spot for an alfresco latte and a slice of cake.
