Quite how the latter name orginated is unclear, because it is its neighbour, the Peirson, which nestles in the corner of the Royal Square. The original name is said to refer to the availability of draught and bottled ales, the former supplied from the 'cock' (tap).
Before it became the Cosy Corner, the establishment was know for a time as The Central, a reference to its position between the Peirson and the property on the other side where the offices of the Jersey Chamber of Commerce were situated for many years.
