In the deli At the Brass Rail One of London’s most famous delis, Selfridge’s The Brass Rail is a shrine to all things salt beef. Last year it got a brand new look and a new ordering system but the salt beef – supplied by Hensons for many years – remains the same as it ever was. Deliciously pink and served in generous juicy slabs. The Brass Rail salt beef sandwich is a classic.
