the Corner Post. It's in a former post office, hence the name and the postbox in their badge, and is a short walk from the Blundellsands & Crosby railway station. Work has been going on since April and they hope to open soon.
It's at 25 Bridge Road, Brighton le Sands, L23 6SA. I have an old friend who lives nearby and we'll visit when it opens: more info then.
Brighton le Sands is an area surrounded by Blundellsands, Crosby and Waterloo, and is a name that that I'd thought was falling into disuse.
P.S. (23 July): the Corner Post opened for business yesterday.
