The Exile of Erin, in Manchester, just off Oldham Road... that definitely was Irish, back in the 70s. Long demolished. The Manchester Irish pubs, like those in Camden Town, catered for those working over here, hence they were usually deserted during the week- most of the clientele being too knackered after a 14 hour day shifting concrete to go for a drink. But at weekends, the ceack was fast, long and hard. A 3 o'clock Sunday morning finish was normal.
As for the chain Irish pubs that sprang up in the 90s, they are thankfully mostly gone now, being Seltic is out of fashion again.
