Champagne Bar opened circa 2003. It became the Red Tent, circa 2011.
The Red Tent didn’t last that long and within a couple of years became Duffy’s Bar. It’s not in Ireland, but it certainly had the flavour, and by 2015, Duffy’s had moved further up Pocklington’s Walk to no 18, the Old Town Arms.
Duffy’s Bar is still very much open for business, as of writing.
