Time Out says
Zagreb’s off-street courtyards remain a much-underused resource, one of many urban attributes which are talked about with great affection but which rarely seem to take off. Which is why courtyard cafés like Regular Bar are such a good thing, drawing customers into a cute passageway diagonally opposite the Britanski trg market. It’s primarily a coffee bar and a lot of effort has gone into getting this just right: the brews are good, the décor goes for a cool uncluttered Sixties feel that hits the right balance between modernity and nostalgia, and service comes with an added citrus twist - patrons are provided with (free) jugs of drinking water flavoured with slices of lemon and lime. The tree-shaded terrace makes for a great off-street hideaway, while DJ events provide reasons to push the boat out on weekend evenings.
