My wife's from Chester - can't remember the name of the district but it's the bit over the bridge near a bakers shop called Weinholts. We live on the south coast now, but went to a folk club in a pub opposite Chester station about 20yrs ago - would that be the Union Vaults mentioned by Dave?? I still remember the session now, it was a friendly place and we were made very welcome by the regulars - can't remember what I sang though...
