Four One One is a bespoke mobile bar hire service born out of cult Hackney bar Behind This Wall. We offer peripatetic packages to events across London and beyond.

Drawing from our experience in pop-ups, logistics and bar management, we can bring our unique approach to your cocktail party, warehouse wedding, or not-so-corporate event, offering our signature drinks, custom bars and friendly service.

Behind This Wall started life without a permanent space: from a Plastic People residency to popping up in an old pie and mash shop; we’ve run festival stages in the Welsh woods, shaken up drinks on a school roof, and settled in for summer-long terrace takeovers.

In 2016 we carried that true independent spirit into bricks and mortar, banded together to open the bar on Mare Street, it is now established as a favoured haunt to those in the know. Interested?
