The Columbo Group, the pub operator run by Steven Ball and Riz Shaikh, is to launch the Blues Kitchen late-night bar in Camden in October. The company has acquired the former Oh Bar on Camden High Street and will open it as a blues bar featuring live music seven nights a week. The group owns four other pubs in London including Paradise by Way of Kensal Green, Albert & Pearl in Highbury & Islington, the Old Queens Head in Angel and the Westbury in Kilburn.
