I can't find my map I got for Liverpool but here is what the local Camra guys gave me.
'For Liverpool, there is the city area (Ship & Mitre, Dr Duncan's, The Dispensary, The Roscoe Head, The White Star...) while in the area near the Anglican Cathedral, you could visit the Philharmonic, Fly in the Loaf, Ye Cracke, Peter Cavanagh's, The Swan...'
I got to most of those. Some were really good and at worst some were good. All walk-able too.
