Manchester - needless to say - has several. I like the Moon Under Water*, on Deansgate, which is a barrel-ceiling ex-cinema, previously theatre. Not nearly so stunning as the Llandudno one pictured above!
The one at Piccadilly is a brown nightmare of a place: it must have the highest-ever ratio of toilet-users to paying-customers of any bar in the country!
Trouble is that you stand a better chance of getting a fresh pint in them than anywhere else.
*This one breaks their usual rule and has - or had - loud music at the weekends!
