Resto 20 El Rincón, Holloway Road
Let's be honest, Holloway Road isn't a conventional choice for outdoor dining. Even in these ULEZ days I should think the atmosphere is only marginally healthier than a Saturday night in Thundersley Snooker Club in 1985. But it does offer a generous parade of north London life and you certainly didn't get that level of variety back in Thatcherite Essex.
